Procedure

To a stirred solution of N-methyl-N-methoxy cyclohexanecarboxamide (7.42 mmol) in 30 mL of tetrahydrofuran at 0° C. under nitrogen was added a solution of benzyl magnesium chloride (2.0 M in tetrahydrofuran, 4.5 mL, 9.0 mmol). The mixture was stirred at 0° C. for 30 minutes and at room temperature for 1 hour. Diethyl ether (50 mL) and water (20 mL) were added. The organic layer was separated, dried, filtered, and concentrated. Purification of the residue by flash chromatography using hexanes and ethyl acetate gave cyclohexyl benzyl ketone (1.05 g) in 70% yield as oil.
