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 (10 g), a 2M ethanolic solution of sodium ethylate (17.5 cc) and ethyl (n-butylthio)acetate (6.16 g) in ethanol (60 cc). Diethyl 2-dimethylamino-5-n-butylthio-2,4-hexadienedioate (10 g) is thereby obtained in the form of an orange-red oil, and is used in the crude state in the subsequent syntheses.
