Reaction Steps

A sample of 5-bromo-4-(p-chlorophenyl)pyrrole-2-carbonitrile (2.2 g., 0.0078 mol) is dissolved in 30 mL of dry dioxane. The solution is heated with bromine (1.3 g., 0.008 mol) in dioxane (20 mL) and then stirred overnight at room temperature. The reaction mixture is poured into water precipitating a tan solid (2.6 g., 92%). A portion (1.6 g) is purified by flash chromatography using 75/25 hexane/ethyl acetate to give 0.8 g of grey solid with m.p. 191°-194° C.
