Procedure
A sample of 5-bromo-2-(3,4-dichlorophenyl)pyrrole-3-carbonitrile (0.158 g, 0.005 mole) is dissolved in tetrahydrofuran (5 mL). An equivalent amount of t-butyl hypochlorite is added and the solution stirred overnight. The solution is poured into water and the precipitate (0.052 g, 30%) is collected. The mp is >275° C. In a similiar fashion one can prepare 2-bromo-3-chloro-5-(3,4-dichlorophenyl)-4-nitropyrrole by starting with 2-bromo-5-(3,4-dichlorophenyl)-4-nitropyrrole.
