Procedure

A sample of 5-(p-chlorophenyl)pyrrole-2,4-dicarbonitrile (1.0 g, 0.004 mole) is dissolved in 20 mL of dioxane and a solution of bromine (0.8 g, 0.005 mole) in dioxane (10 mL) is then added thereto. The solution is stirred several hours at room temperature and then poured into water precipitating a white solid (1.2 g, 100%). The solid has a m.p. >225° C. and a mass spectrum of a sample gives a pattern consistent with the desired structure.
