実験手順

A mixture of 112a (140 mg, 0.20 mmol), NaBH4 (21 mg, 0.60) and CH3OH (8 mL) was stirred at 25° C. for 1 h. Then the reaction mixture was quenched with water (10 mL), the mixture was extracted with CH2Cl2 (15 mL×2). The combined CH2Cl2 extract was concentrated under reduced pressure. The residue was purified with reverse-phase prep-HPLC to afford 112 (70 mg, 50%).
