Procedure

A mixture of 206g (93.6 mg, 0.15 mmol) and lithium hydroxide (65 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 diluted with water (3 mL). It was then extracted with ethyl acetate (2×10 mL). The combined ethyl acetate extract was concentrated under reduced pressure and the residue was purified by reverse-phase prep-HPLC to afford 206 (35 mg, 42%) as white solid.
