反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 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 benzylmercaptan (11.7 cc). Ethyl (benzylthio)acetate (19.4 g) is thereby obtained, and is used in the crude state in the subsequent phases.

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

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 (15.7 g), a 2M ethanolic solution of sodium ethylate (27.5 cc) and ethyl (benzylthio)acetate (11.6 g) in ethanol (110 cc). Diethyl 5-benzylthio-2-dimethylamino-2,4-hexadienedioate (19.2 g) is thereby obtained, and is used in the crude state in the subsequent phases.

実験手順: To a solution of benzyl mercaptan (1.18 mL, 10.0 mmol) in DMF (20 mL) is added potassium carbonate (1.51 g, 10.9 mmol) and ethyl bromoacetate (1.17 mL, 10.6 mmol), and the mixture is stirred at RT for 25 min. Et2O is added, and the mixture is washed with water, brine, then dried (MgSO4), and filtered. The filtrate is evaporated, and the residue is vacuum distilled (130-140° C.) to give 1.05 g of the product 402. the mixture is washed with water, brine dried (MgSO4) filtered The filtrate is evaporated distilled (130-140° C.)
