The mixture was then cooled, diluted with water and extracted with ethyl acetate. The organics were combined, washed with water, brine, dried over MgSO4, and concentrated. Flash chromatography (0%-100% ethyl acetate in hexane) afforded N-[4-(5-cyano-1-methyl-1H-pyrrol-2-yl)-2,5-difluorophenyl]propane-2-sulfonamide (26 mg).
