Furan-2-carbonyl chloride (54 μL, 0.55 mmol) was added and the mixture was stirred 16 hours. The mixture was diluted with 50% ether in ethyl acetate and washed with water, saturated NaHCO3, 2N HCl, brine, dried over MgSO4, and passed through a plug of silica gel. The solution was concentrated to give N-[4-(5-cyano-1-methyl-1H-pyrrol-2-yl)phenyl]-2-furamide (0.041 g).
