Versuchsvorschrift

To a solution of 122c (150 mg, 0.25 mmol) in THF/i-propanol/water (2.5/1/0.5 mL) was added lithium hydroxide (70 mg, 2.5 mmol) at 35° C. After the reaction was stirred for 3 h, LCMS indicated the reaction was completed. The mixture was poured into water (15 mL) and extracted with dichloromethane (3×20 mL). The combined organic layer was washed with brine (30 mL), dried over Na2SO4, filtered, and concentrated under reduced pressure. The residue solid was purified by reverse-phase prep-HPLC to afford 122 (49 mg, 35%) as a white solid.
