反応手順
To a tetrahydrofuran solution containing 1.78 g (6.6 mmole) of 2-(4-chlorophenyl)-5-phenylvaleronitrile was added a tetrahydrofuran solution containing 0.77 g (6.9 mmole) of potassium tert-butoxide at 0° C. After stirring for 30 minutes, a tetrahydrofuran solution containing 0.5 g (6.8 mmol) of methyl isothiocyanate was added to the mixture and the mixture was stirred at room temperature for 2 hours. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate, dried and condensed under reduced pressure, and then purified by silica gel chromatography to obtain 1.19 g (yield: 52.4 %) of N-methyl-2-(4-chlorophenyl)-2-cyano-5-phenylthiovaleroamide as a crystal.
