实验步骤: The procedure is as in Example 2 for the preparation of ethyl (phenylthio)acetate starting with ethyl bromoacetate (16.7 g), a 2M ethanolic solution of sodium ethylate (50 cc) and 4-chlorothiophenol (14.5 g). Ethyl (4-chlorophenylthio)acetate (20.7 g) is thereby obtained, and is used in the crude state in the subsequent phases.

实验步骤: 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 (14.3 g), a 2M ethanolic solution of sodium ethylate (25 cc) and ethyl (4-chlorophenylthio)acetate (11.5 g) in ethanol (100 cc). Diethyl 5-(4-chlorophenylthio)-2-dimethylamino-2,4-hexadienedioate (19 g) is thereby obtained, and is used in the crude state in the subsequent phases.
