Procedure
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 (5.5 g), a 2M ethanolic solution of sodium ethylate (9.7 cc) and ethyl (allylthio)acetate (3.1 g) in ethanol (31 cc). Diethyl 5-allylthio-2-dimethylamino-2,4-hexadienedioate (5.1 g) is thereby obtained, and is used in the crude state in the subsequent phases.
