実験手順

To a solution of 261a (90.0 mg, 0.17 mmol) in methanol (5 mL) was added sodium borohydride (64.6 mg, 1.7 mmol) at room temperature. The reaction was stirred for 0.5 h. It was then quenched with water (2 mL) and evaporated in vacuo. The residue was extracted with dichloromethane (3×10 mL). The combined dichloromethane extract was concentrated under reduced pressure and the residue was purified by reverse-phase prep-HPLC to afford 261 (47.0 mg, 52%) as a white solid.
