A solution of 25 g of o-nitrocinnamic acid in 250 ml of ethanol was shaken with 2.5 g of 10% palladium on carbon under hydrogen at a pressure of 3 atmospheres. When the theoretical amount of hydrogen had been absorbed the catalyst was filtered off, washed with hot ethanol and the filtrate evaporated under reduced pressure to give 3,4-dihydrocarbosytril, m.p. 168°-169° C.
