Reaction Steps

To a solution of 4-(4-methylphenyl)pyrrole-3-carbonitrile (2.0 g) in a mixture of benzene (40 ml) and aqueous sodium hydroxide solution (10 ml) was added methyliodide (1.56 g) and tetrabutylammonium iodide (4.06 g) in that order in an ice bath. The mixture was stirred for 3 hours at ambient temperature and extracted twice with diethyl ether. The combined organic layers were washed with aqueous hydrochloric acid and then water, dried, and concentrated in vacuo to yield 1-methyl-4-(4-methylphenyl)pyrrole-3-carbonitrile (2.03 g) as pale yellow crystals.
