Participants

Reaction Steps

A mixture of 30.0 g. of 4-(p-chlorocinnamamido)benzoic acid, ethyl ester, 500 mg. of 10% palladium on carbon, and 150 ml. of tetrahydrofuran is hydrogenated in a Parr apparatus, over a 2 hour period, repressurizing until hydrogen uptake is complete. The mixture is filtered, and the filtrate is evaporated. The solid is crystallized from 175 ml. of ethanol, giving 26.8 g. of the desired product as white crystals, m.p. 163°-165° C.
