反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: The procedure is as in Example 29 for the preparation of ethyl (4-methylbenzylthio)acetate, starting with iodoethane (10.5 g), a 2M ethanolic solution of sodium ethylate (37 cc) and ethyl 2-mercaptoacetate (8.1 g) in ethanol (100 cc). Ethyl (ethylthio)acetate (6.9 g) is thereby obtained, and is used in the crude state in the subsequent syntheses.

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 (10 g), a 2M ethanolic solution of sodium ethylate (21 cc) and ethyl (ethylthio)acetate (5.2 g) in ethanol (100 cc). Diethyl 2-dimethylamino-5-ethylthio-2,4-hexadienedioate (8.5 g) is thereby obtained in the form of a red oil, and is used in the crude state in the subsequent syntheses.
