Procedure

A mixture of 200f (260 mg, 0.39 mmol) and lithium hydroxide (92.4 mg, 3.85 mmol) in THF (9 mL), isopropanol (6 mL), and water (1 mL) was stirred at room temperature for 0.5 h. The mixture was extracted concentrated under reduced pressure and diluted with water (4 mL). It was then extracted with dichloromethane (2×10 mL) and the combined C dichloromethane extract was concentrated under reduced pressure. The residue was purified with reverse-phase prep-HPLC to afford 200 (53.1 mg, 20%) as yellow solid.
