Procedure

A mixture of 5.0 g. of 4-nitrocinnamic acid and 100 mg. of 10% palladium-on-carbon in 200 ml. of ethanol containing 5 drops of 5.5N ethanolic hydrogen chloride is treated with hydrogen in a Parr apparatus at room temperature for 3 hours. The mixture is then filtered through celite and the filtrate is evaporated, affording 4-aminohydrocinnamic acid.
