Reaction Steps
To a solution of 1-(diethoxymethyl)-1H-imidazole (935 mg, 5.5 mmol) in anhydrous tetrahydrofuran (6 ml), at −78° C., was added n-butyllithium (2.5M in hexanes, 2.2 ml, 5.5 mmol). The mixture was allowed to warm to 0° C. and then added to a solution of 1-(3-methylphenyl)ethanone (670 mg, 5.0 mmol) in anhydrous tetrahydrofuran (5 ml), also at 0° C. The reaction mixture was stirred at 0° C. for 30 min and then at room temperature for 1 h. The mixture was poured into cold hydrochloric acid (4N, 10 ml) and stirred for 20 min. The mixture was adjusted to pH 7 by addition of sodium hydrogen carbonate and then extracted with dichloromethane. The combined extracts were dried (MgSO4) and concentrated in vacuo to give the title compound (850 mg).
