Participants

Reaction Steps

A mixture of 3,4-dichloro-1-(4-methylphenyl)pyrrole-2-carbonitrile (1.25 g), 2,2'-azobisisobutyronitrile (10 mg) and N-bromosuccinimide (1.068 g) in carbon tetrachloride (25 ml) was refluxed for 3 hours, cooled to ambient temperature, and filtered. The filtrate was concentrated in vacuo. The residue was crystallized from 10% ethyl acetate in n-hexane to yield 1-(4-bromomethylphenyl)-3,4-dichloropyrrole-2-carbonitrile (1.01 g).
