Procedure

A mixture of 3-phenylcyclopentanone (1.3 g, 8.12 mmol) and NaBH4 (0.61 g, 16.24 mmol) in methanol (15 mL) was stirred at room temperature for 1 h. The mixture was concentrated, dissolved in CH2Cl2, washed with 10% HCl, brine, dried over MgSO4 and concentrated to afford the title compound as a white solid. MS m/z: 163 (M+1).
