To a solution of 16.4 g (0.2 mol) of 3-aminocrotononitrile in 100 cm3 of n-pentanol were added 19.4 g (0.22 mol) of tert-butylhydrazine. This solution was heated at reflux for 20 hours. The n-pentanol was subsequently distilled off under reduced pressure. A pale yellow solid was obtained, which was taken up in 100 cm3 of isopropyl ether at room temperature and filtered on a sinter funnel. After drying under vacuum at 40° C., 18 g of the expected product were obtained in the form of a pale yellow solid, the melting point of which was from 172 to 175° C.
