Hydrochloric Acid → 2-(4-Isobutyrylphenyl)ethyl acetate

참여 물질

반응 단계

Isobutyryl chloride (114 g, 1.07 mol) is added drop wise at −5 to 0° C. over 40 minutes to 295 g (2.21 mol) of anhydrous aluminum chloride in 160 ml of methylene chloride. Stirring is continued for 30 min, and 2-phenylethyl acetate (164.2 g, 1.00 mol) is then added drop wise at −5 to 0° C. over 2 hours. The mixture is stirred an additional 4 hours at −5 to 0° C., and then poured into a mixture of concentrated hydrochloric acid and ice. The organic layer is washed with water, dried and concentrated to give 190.5 g of crude 2-(4-isobutyrylphenyl)ethyl acetate, a colorless liquid.
