Reaction Steps

Compound 52 (1.65 g, 4.93 mmol) was dissolved in THF (30 mL), then the solution was added with 2 mol/L aqueous sodium hydroxide solution (15.0 mL) at 0° C., followed by stirring at 70° C. for 1 hour. The reaction mixture was neutralized with 2 mol/L hydrochloric acid, then was extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, and was concentrated. The residue was recrystallized from ethyl acetate and methanol to obtain Compound 53 (662 mg, 42%).
