Reaction Steps
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 (28.6 g), a 2M ethanolic solution of sodium ethylate (50 cc) and ethyl (methylthio)acetate (13.4 g) in ethanol (180 cc). Diethyl 2-dimethylamino-5-methylthio-2,4-hexadienedioate (21.9 g) is thereby obtained in the form of a brown oil, and is used in the crude state in the subsequent syntheses.
