Hydrochloric Acid → 1-Benzylpiperidine-4-acetonitrile

참여 물질

반응 단계

To a solution of benzylpiperidin-4-ylideneacetonitrile (compound of Example 26; 1 g, 4.7 mmol) in methanol (50 mL), magnesium turnings (4.58 g, 188.3 mmol) was added at 0° C. The reaction mixture was stirred at 5° C. to 10° C. for 4 h. The magnesium salts were dissolved by addition of concentrated hydrochloric acid, and the mixture was basified with 10N sodium hydroxide solution. The precipitate was filtered and extracted with ethyl acetate (2×20 mL). The combined organic layers were washed with water (2×15 mL) followed by brine (10 mL). The organic phase obtained was dried over anhydrous sodium sulphate and evaporated to afford the title compound.
