Reaction Steps

A mixture of 7.0 g of 2,4,5-tribromopyrrole-3-carbonitrile and 2.9 g of potassium t-butoxide in tetrahydrofuran is treated with 13.8 g of phenyl chloroformate, heated at reflux temperature for 12 hours, cooled, poured into water and filtered. The solid filter cake is washed with water and dried in vacuo to afford the title compound. A sample is recrystallized from a mixture of ethyl acetate and methylcyclohexane to give colorless crystals, mp 128°-129° C.
