Triethylamine → 1-(4-Benzyloxyphenyl)-2-(4-diphenylmethylpiperazinyl)ethanone

참여 물질

반응 단계

To 90 ml of an ethyl acetate solution containing 7.56 g (30 mmol) of 1-diphenylmethylpiperazine and 3.33 g (33 mmol) of triethylamine was added 9.15 g (30 mmol) of p-benzyloxy-α-bromoacetophenone. The resultant mixture was stirred at room temperature for 45 minutes. After addition of 100 ml of ice water, the thus obtained mixture was stirred for about 10 minutes. Precipitated crystals were collected by filtration and then washed successively with water, ethanol and ethyl acetate and thereafter dried to give 12.5 g of 1-(4-benzyloxyphenyl)-2-(4-diphenylmethylpiperazinyl)ethanone (yield: 87.4%).
