A solution of 1-dimethylamino-4-[1-(1-ethoxy-ethoxy)-2-phenoxyethyl]cyclohexanecarbonitrile (871 mg, 2.4 mmol) in anhydrous tetrahydrofuran (15 ml) was added dropwise to a 2 M solution of phenylmagnesium chloride in tetrahydrofuran (3.6 ml, 7.3 mmol), while cooling with ice. The mixture was stirred at room temperature overnight and saturated ammonium chloride solution and water (5 ml of each) were then added. The phases were separated and the aqueous phase was extracted with diethyl ether (3×20 ml). The combined organic phases were dried with sodium sulfate and concentrated in vacuo.
