Reaction Conditions

Reaction Steps

To a solution of 3-methoxybenzylmagnesium chloride (19.8 mole) in tetrahydrofuran (20 ml) was added a mixture of 2-cyclohexen-1-one (1.9 g) and trimethylsilyl chloride (5.8 ml) in tetrahydrofuran (30 ml) at -78° C. under N2. The mixture was stirred for 1 hour at 0° C. The reaction mixture was poured into a mixture of ethyl acetate and 1N-hydrochloric acid and the organic layer was washed with saturated sodium bicarbonate aqueous solution and brine. The combined organic extracts were concentrated and the residue was purified by column chromatography on silica gel to give 3-(3-methoxybenzyl)cyclohexanone (2.12 g).
