Procedure

1.0 g of magnesium turnings are covered with 5 ml of dry tetrahydrofuran. To the mixture is added 7.8 g of (2-bromoethyl)benzehe in 30 ml of dry tetrahydrofuran at such a rate that a smooth reaction is maintained. The mixture is then heated under reflux for one hour. After being cooled to room temperature, 3.0 g of 1-(3-benzyl-3H-imidazol-4-yl)-ethanone in 20 ml of tetrahyrofuran is added dropwise to the Grignard reagent and the reaction mixture is refluxed for one hour. The cooled reaction mixture is poured into a cold dilute hydrochloric acid solution. Work-up of the mixture gives the crude product, which is recrystallized from ethyl acetate. The yield is 3.3 g.
