Reaction Steps

To a chilled suspension of 26.80 g. (0.2 mole) of aluminum chloride in 110 ml. of methylene chloride is added dropwise 35 g. (0.2 mole) of p-chlorobenzoyl chloride. The mixture is added dropwise to a solution of 21.22 g. (0.2 mole) of pyrrole-2-acetonitrile in 125 ml. methylene chloride which is cooled externally with an ammonium chloride ice bath. After addition is complete, the reaction mixture is stirred for ten minutes at 0°C. and then poured into ice acidified with dilute hydrochloric acid. A solid precipitate, 5-(p-chlorobenzoyl)-pyrrole-2-acetonitrile, which is filtered off, washed with hot methanol and dried, m.p. 203°-205°C.
