Procedure
A mixture of 244d (90 mg, 0.15 mmol) and lithium hydroxide (60 mg, 1.5 mmol) in THF/i-propanol (5:3, 8 mL) and water (2 mL) was stirred at 30° C. for 1 h. The mixture was evaporated in vacuo and the residue was diluted with water (3 mL). It was then extracted with ethyl acetate (20 mL×2). The combined ethyl acetate extract was concentrated under reduced pressure and the residue was purified by reverse-phase prep-HPLC to afford 244 (25 mg, 30%) as white solid.
