To the solution of 103c (500 mg, 0.8 mmol) in methanol (50 mL) was added sodium borohydride (91 mg, 2.4 mmol) at 0° C. and stirred for another 30 minutes. Then the reaction mixture was quenched with water (3 mL) and concentrated. The residue was purified with reverse-phase prep-HPLC to afford 103 (224 mg, 45%).
