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-phenylpropenylidene)-N-methylmethanaminium tetrafluoroborate (15.4 g), a 2M solution of sodium ethylate (26.5 cc) and ethyl (phenylthio)acetate (10.4 g) in ethanol (150 cc). After purification by chromatography on a silica column with dichloromethane as eluent, ethyl 5-dimethylamino-5-phenyl-2-phenylthio-2,4-pentadienoate (9.7 g), m.p. 99° C., is obtained.
