Procedure

To a solution of 322a (136 mg, 0.20 mmol) in THF/i-propanol/water (4/2/1 mL) was added lithium hydroxide (48 mg, 2.0 mmol) at room temperature. After the reaction was stirred for 2 h, LCMS indicated the reaction was complete. Then the mixture was poured into water (15 mL) and extracted with dichloromethane (3×15 mL). The combined organic layer was washed with brine (30 mL), dried over Na2SO4, filtered, and concentrated under reduced pressure. The residue was purified by reverse-phase prep-HPLC (A: 1% NH4HCO3/water, B: acetonitrile) to afford 322 (50 mg, 40%) as a white solid.
