実験手順
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 (5.7 g), a 2M ethanolic solution of sodium ethylate (50 cc) and ethyl (4-trifluoromethylbenzylthio)acetate (5.6 g) in ethanol (50 cc). Diethyl 2-dimethylamino-5-(4-trifluoromethylbenzylthio)-2,4-hexadienedioate (7.3 g) is thereby obtained in the form of a yellow oil, and is used in the crude state in the subsequent syntheses.
