Procedure

Hydroxylamine hydrochloride (25.4 mg, 0.4 mmol) was added to a solution of intermediate (5c) (174 mg, 0.3 mmol), pyridine (3 mL, 37 mmol) and water (1.5 mL, 83 mmol) at room temperature. After 15 minutes, water (10 mL) was added and the mixture was extracted with EtOAc (3×20 mL). The combined organic extracts were washed with saturated aqueous NaCl (10 mL), dried over MgSO4, filtered, and concentrated in vacuo. Silica gel chromatography gave intermediate (5d) as a white solid (148 mg).
