Yield: 94%

Reaction Conditions:

with copper in water at 100; for 18 h;

Steps:


To the pressure-resistant tube was added 4-bromoacetophenone 5 g (25.12 mmol), copper powder 0.08 g (1.26 mmol) aqueous methylamine solution (13 mL, 30%). The pressure tube seal was heated to 100 ° C in an oil bath for 18 h, and the reaction solution was cooled to room temperature, then extracted with ethyl acetate (3×100 mL), the organic phase was combined, washed with brine, dried over anhydrous sodium sulfate Development solvent petroleum ether: ethyl acetate = 5:1, 200-300 mesh silica gel column chromatography to give compound 33.53 g, yield 94%
