Reaktionsschritte
The procedure is as in Example 2 for the preparation of diethyl 2-dimethylamino-5-phenylthio-2,4-hexadienedioate, starting with N-(3-dimethylamino-3-ethoxycarbonylpropenylidene)-N-methylmethanaminium tetrafluoroborate (57.2 g), a 2M ethanolic solution of sodium ethylate (105 cc) and benzyl cyanide (23.4 g). Ethyl 2-dimethylamino-5-cyano-5-phenyl-2,4-pentadienoate (36.1 g), m.p. 67° C., is obtained.
