Versuchsvorschrift

To a stirred solution of methylmagnesium bromide (60 mL of a 3.0 M solution in diethyl ether) at 0° C. was added dropwise a solution of 3-bromoacetophenone (29.8 grams) in 75 mL of diethyl ether. Once the addition was complete, the mixture was stirred for 0.5 hours and poured into water. The aqueous phase was acidified with 1M hydrochloric acid and extracted with three portions of diethyl ether. The combined ether layers were washed with saturated sodium bicarbonate, concentrated to afford 30.4 grams of the title compound. 1H NMR δ7.72 (br s, 1), 7.49 (d, 1, J=7.8), 7.37 (d, 1, J=7.9), 7.25 (dd, 1, J=7.8, 7.9), 4.19 (s, 1), 1.50 (br s, 6).
