実験手順: (2-Methanesulfonylaminophenyl)acetonitrile (300 mg) was mixed with 10% palladium/carbon (catalytic amount) in methanol (20 ml) and the mixture was stirred under hydrogen gas atmospheres for 48 hours. After confirming the completion of the reaction using TLC, the resulting mixture was filtered through celite and the filtrate was concentrated under reduced pressure. The following procedure was carried out using the concentrate which was not purified. the resulting mixture was filtered through celite the filtrate was concentrated under reduced pressure concentrate which was not purified

実験手順: To an ice-cold solution of 2-aminophenylacetonitrile (500 mg) in dichloromethane (20 ml) were added triethylamine (330 μl) and methanesulfonyl chloride (530 μl) and the mixture was stirred for 16 hours, under argon gas atmosphere. After confirming the completion of the reaction using TLC, the resulting mixture was diluted with 1 N aqueous hydrochloric acid solution (30 ml), and extracted with dichloromethane (50 ml×3). The organic layer was washed with brine, dried over magnesium sulfate, and then filtered. The filtrate was concentrated under reduced pressure and the obtained residue was purified by column-chromatography (ethyl acetate/hexane=1/2) to yield (2-methanesulfonylaminophenyl)acetonitrile (573 mg, 72%). extracted with dichloromethane (50 ml×3) The organic layer was washed with brine dried over magnesium sulfate filtered The filtrate was concentrated under reduced pressure the obtained residue was purified by column-chromatography (ethyl acetate/hexane=1/2)
