Procedure

To a solution of 121h (150 mg, 0.22 mmol) in methanol (10 mL) was added NaBH4 (41.8 mg, 1.1 mmol) at room temperature. After the reaction was stirred for 1 h, LCMS indicated the reaction was complete. The mixture was poured into water (30 mL) and concentrated under reduced pressure. The residue was extracted with dichloromethane (3×30 mL). The combined organic layer was washed with brine (30 mL), dried over Na2SO4, filtered, and concentrated under reduced pressure. The residue solid was purified by prep-HPLC to afford 121 (60.3 mg, 40%) as white solid.
