Procedure

To a solution of cyclopentanon 23 (60 mg, 0.16 mmol) in 1 mL of MeOH and 0.5 mL of THF was added NaBH4 (15 mg, 0.40 mmol). After stirring for 2 hrs saturated aqueous ammonium chloride was added. The solution was diluted with EtOAc. The aqueous solution was extracted 2× with EtOAc. The combined organic extracts were washed with brine, dried over Na2SO4, filtered and concentrated to give 60 mg (0.16 mmol, 100%) of alcohol 25. HRMS (ES+) calc for C22H30NO6: 404.2073, found: 404.2082 (M+NH4).
