Reaction Steps

5-[4-amino-2-(trifluoromethyl)phenyl]-1-methyl-1H-pyrrole-2-carbonitrile (0.34 g, 1.3 mmol) was dissolved in CH2Cl2 (5 mL) and pyridine (0.2 mL). Methanesulfonyl chloride (90 μL, 1.2 mmol) was added and the mixture was stirred for 16 hours followed by the addition of water. The mixture was then diluted with ethyl acetate, the mixture was washed with water, 2N HCl, brine, dried over MgSO4, and concentrated. The crude product was purified via Isco chromatography (the Redisep® column, silica, gradient 5-50% ethyl acetate in hexane) to afford 0.29 g of N-[4-(5-cyano-1-methyl-1H-pyrrol-2-yl)-3-(trifluoromethyl)phenyl]-methanesulfonamide.
