90 g of β-(2,5-Dimethoxyphenyl)acrylonitrile and 500 ml of ethanol containing about 100 g of ammonia were subjected to catalytic reduction inthe presence of Raney nickel under a hydrogen pressure of 80 atm. and at 130° C for 3 hours. After the reaction, distillation under reduced pressure gave 82 g of the end product having a boiling point of 105° ~ 107° C/l mmHg (yield 88.2%).
