Reaktionsschritte

5-(4-amino-2-fluorophenyl)-1-methyl-1H-pyrrole-2-carbonitrile (0.20 g, 0.93 mmol) was dissolved in pyridine (2.0 mL). Methanesulfonyl chloride (0.07 mL, 0.9 mmol) was added and the mixture was stirred for 16 hours, followed by the addition of water. The mixture was diluted with ethyl acetate and then was washed with water, saturated CuSO4, 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 0.18 g of N-[4-(5-cyano-1-methyl-1H-pyrrol-2-yl)-3-fluorophenyl]methanesulfonamide.
