Currently, angiotensin II receptor antagonists and calcium antagonists are widely used as a medicament for the treatment or prevention of such hypertension or heart disease.Mineralocorticoid receptor (MR) (aldosterone receptor) has been known to play an important role in the control of body electrolyte balance and blood pressure, spironolactone having a steroid structure, MR antagonists such as eplerenone, are known to be useful in the treatment of hypertension-heart failure.Renin – angiotensin II receptor antagonists are inhibitors of angiotensin system is particularly effective in renin-dependent hypertension, and show a protective effect against cardiovascular and renal failure. Also, the calcium antagonists, and by the function of the calcium channel antagonizes (inhibits), since it has a natriuretic action in addition to the vasodilating action, is effective for hypertension fluid retention properties (renin-independent) .Therefore, the MR antagonist, when combined angiotensin II receptor antagonists or calcium antagonists, it is possible to suppress the genesis of multiple hypertension simultaneously, therapeutic or prophylactic effect of the stable and sufficient hypertension irrespective of the etiology is expected to exhibit.Also, diuretics are widely used as a medicament for the treatment or prevention of such hypertension or heart disease. Diuretic agent is effective in the treatment of hypertension from its diuretic effect. Therefore, if used in combination MR antagonists and diuretics, the diuretic effect of diuretics, it is possible to suppress the genesis of multiple blood pressure at the same time, shows a therapeutic or prophylactic effect of the stable and sufficient hypertension irrespective of the etiology it is expected.1- (2-hydroxyethyl) -4-methyl -N- [4- (methylsulfonyl) phenyl] -5- [2- (trifluoromethyl) phenyl] -1H- pyrrole-3-carboxamide (hereinafter, compound ( I)) is, it is disclosed in Patent Documents 1 and 2, hypertension, for the treatment of such diabetic nephropathy are known to be useful.
CS-3150 (XL550) is a small-molecule antagonist of the mineralocorticoid receptor (MR), a nuclear hormone receptor implicated in a variety of cardiovascular and metabolic diseases. MR antagonists can be used to treat hypertension and congestive heart failure due to their vascular protective effects. Recent studies have also shown beneficial effects of adding MR antagonists to the treatment regimen for Type II diabetic patients with nephropathy. CS-3150 is a non-steroidal, selective MR antagonist that has the potential for the treatment of hypertension, congestive heart failure, or end organ protection due to vascular damage.
Useful as a mineralocorticoid receptor (MR) antagonist, for treating hypertension, cardiac failure and diabetic nephropathy. It is likely to be CS-3150, a non-steroidal MR antagonist, being developed by Daiichi Sankyo (formerly Sankyo), under license from Exelixis, for treating hypertension and diabetic nephropathy (phase 2 clinical, as of March 2015). In January 2015, a phase II trial for type 2 diabetes mellitus and microalbuminuria was planned to be initiated later that month (NCT02345057).
Exelixis discovered CS-3150 and out-licensed the compound to Daiichi-Sankyo. Two phase 2a clinical trials, one in hypertensive patients and the other in type 2 diabetes with albuminuria, are currently being conducted in Japan by Daiichi-Sankyo.

Daiichi Sankyo (formerly Sankyo), under license from Exelixis, is developing CS-3150 (XL-550), a non-steroidal mineralocorticoid receptor (MR) antagonist, for the potential oral treatment of hypertension and diabetic nephropathy, microalbuminuria , By October 2012, phase II development had begun ; in May 2014, the drug was listed as being in phase IIb development . In January 2015, a phase II trial for type 2 diabetes mellitus and microalbuminuria was planned to be initiated later that month. At that time, the trial was expected to complete in March 2017 .
Exelixis, following its acquisition of X-Ceptor Therapeutics in October 2004 , was investigating the agent for the potential treatment of metabolic disorders and cardiovascular diseases, such as hypertension and congestive heart failure . In September 2004, Exelixis expected to file an IND in 2006. However, it appears that the company had fully outlicensed the agent to Sankyo since March 2006 .

(Example 3)(+/-)-1-(2-hydroxyethyl)-4-methyl-N-[4-(methylsulfonyl)phenyl]-5-[2-(trifluoromethyl)phenyl]-1H-pyrrole-3-carboxamide
-
After methyl 4-methyl-5-[2-(trifluoromethyl) phenyl]-1H-pyrrole-3-carboxylate was obtained by the method described in Example 16 of WO 2006/012642 , the following reaction was performed using this compound as a raw material.
-
Methyl 4-methyl-5-[2-(trifluoromethyl)phenyl]-1H-pyrrole-3-carboxylate (1.4 g, 4.9 mmol) was dissolved in methanol (12 mL), and a 5 M aqueous sodium hydroxide solution (10 mL) was added thereto, and the resulting mixture was heated under reflux for 3 hours. After the mixture was cooled to room temperature, formic acid (5 mL) was added thereto to stop the reaction. After the mixture was concentrated under reduced pressure, water (10 mL) was added thereto to suspend the resulting residue. The precipitated solid was collected by filtration and washed 3 times with water. The obtained solid was dried under reduced pressure, whereby 4-methyl-5-[2-(trifluoromethyl)phenyl]-1H-pyrrole-3-carboxylic acid (1.1 g, 83%) was obtained as a solid. The thus obtained solid was suspended in dichloromethane (10 mL), oxalyl chloride (0.86 mL, 10 mmol) was added thereto, and the resulting mixture was stirred at room temperature for 2 hours. After the mixture was concentrated under reduced pressure, the residue was dissolved in tetrahydrofuran (10 mL), and 4-(methylsulfonyl)aniline hydrochloride (1.0 g, 4.9 mmol) and N,N-diisopropylethylamine (2.8 mL, 16 mmol) were sequentially added to the solution, and the resulting mixture was heated under reflux for 18 hours. After the mixture was cooled to room temperature, the solvent was distilled off under reduced pressure, and acetonitrile (10 mL) and 3 M hydrochloric acid (100 mL) were added to the residue. A precipitated solid was triturated, collected by filtration and washed with water, and then, dried under reduced pressure, whereby 4-methyl-N-[4-(methylsulfonyl) phenyl]-5-[2-(trifluoromethyl)phenyl]-1H-pyrrole-3-carboxamide (1.4 g, 89%) was obtained as a solid.

Then, 1,3,2-dioxathiolane-2,2-dioxide (0.14 g, 1.2 mmol) was added thereto, and the resulting mixture was stirred at room temperature. After 1 hour, sodium hydride (40 mg, 1.0 mmol, oily, 60%) was added thereto again, and the resulting mixture was stirred for 30 minutes. Then, 1,3,2-dioxathiolane-2,2-dioxide (12 mg, 0.11 mmol) was added thereto, and the resulting mixture was stirred at room temperature for 1 hour. After the mixture was concentrated under reduced pressure, methanol (5 mL) was added to the residue and insoluble substances were removed by filtration, and the filtrate was concentrated again. To the residue, tetrahydrofuran (2 mL) and 6 M hydrochloric acid (2 mL) were added, and the resulting mixture was stirred at 60°C for 16 hours. The reaction was cooled to room temperature, and then dissolved in ethyl acetate, and washed with water and saturated saline. The organic layer was dried over anhydrous sodium sulfate and filtered. Then, the filtrate was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate), whereby the objective compound (0.25 g, 48%) was obtained.
