反応条件

反応手順

Sodium metal (0.8 g, 34.78 mmol) was dissolved in dry methanol (10 mL) at 0-10° C. and this solution was added slowly into a suspension of hydroxylamine hydrochloride (2.43 g, 34.96 mmol) in methanol (10 mL) at room temperature. The reaction mixture was stirred for 10 min until a clear solution was obtained, 2-(1-Benzylpiperidin-4-yl)acetonitrile (compound of Example 27; 3 g, 13.99 mmol) in dry methanol (20 mL) was added into the resulting reaction mixture and heated at 75° C. for 13 h. The solvent was evaporated at 50° C. to 55° C. and the crude product obtained was purified by column chromatography (silica gel, chloroform-methanol) to afford the title compound.
