Versuchsvorschrift

To a solution of 162d (50 mg, 0.080 mmol) in THF/i-propanol/water (1/1/0.5 ml) was added lithium hydroxide (19 mg, 0.80 mmol) at room temperature. After the reaction was stirred for 2.5 h, LCMS indicated the reaction was complete. Then 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 (A: 1% NH4HCO3/water, B: acetonitrile) to afford 162 (15 mg, 33.3%) as white solid.
