Reaction Steps

A solution of 1.6 g of 5-(p-cyanophenyl)-7,8-dihydroimidazo[1,5-a]pyridine in 50 ml of ethyl acetate is hydrogenated at atmospheric pressure with 0.2 g of 5% palladium on charcoal until the theoretical uptake of hydrogen is complete. The catalyst is filtered, and the solvent evaporated to yield the title compound, m.p. 117°-118°.
