Procedure
Under a stream of argon, 6.5 g of 3-bromoacetophenone are placed in a round-bottomed flask and dissolved in 544 ml of diethyl ether and 272 ml of tetrahydrofuran. The mixture is cooled at 0° C. using an ice bath, and 100 ml of a 1M solution of methylmagnesium bromide in dibutyl ether are added thereto, dropwise. The mixture is stirred at 0° C. for 1 h and 400 ml of a saturated aqueous solution of ammonium chloride are added. The organic phase is separated, dried over magnesium sulphate and concentrated under reduced pressure. 10.0 g of compound are obtained.
