Procedure
A solution of 4-[2-(1,3-dihydroisoindol-2-yl)-1-hydroxyethyl]-1-dimethylaminocyclohexanecarbonitrile (666 mg, 2.12 mmol) in anhydrous tetrahydrofuran (30 ml) was added dropwise to a 2 M solution of phenylmagnesium chloride in tetrahydrofuran (4.25 ml, 8.49 mmol), while cooling with ice, and the mixture was stirred at room temperature overnight. Saturated ammonium chloride solution and water (10 ml of each) were then added dropwise to the mixture, while cooling with ice. The tetrahydrofuran was distilled off in vacuo and the residue was extracted with diethyl ether (3×30 ml). The combined organic phases were dried with sodium sulfate and concentrated in vacuo. The crude product (761 mg) was purified by flash chromatography with chloroform/methanol (9:1). Renewed flash chromatography with chloroform (saturated with 25% aqueous ammonia solution)/methanol (95:5) gave a yield of 83 mg (10%) of beige-coloured solid.
