Procedure

A mixture of 101m (135 mg, 0.21 mmol) and NaBH4 (20 mg, 0.5 mmol) in MeOH (5 mL) was stirred at 0° C. for 0.5 h. The mixture was quenched with water and the residue was extracted with EtOAc (5 mL×2). The combined EtOAc extract was concentrated under reduced pressure and the residue was purified with reverse-phase prep-HPLC to afford 101 (55 mg, 40%).
