Procedure

A solution of 167h (120 mg, 0.21 mmol) in methanol (20 mL) was added NaBH4 (24 mg, 0.63 mmol). The mixture was stirred at 20° C. for 2 h. The reaction was quenched with water and concentrated under reduced pressure. The residue was purified by reverse-phase prep-HPLC to afford 167 (98 mg, 83%) as a yellow solid.
