Procedure

To a solution of Compound 8b (89 mg; 0.19 mmol) in CH2Cl2 (7 mL) was added acetyl chloride (0.1 mL) and pyridine (0.1 mL) at ambient temperature. The mixture was stirred at room temperature for 3 h. Diluted the resulted mixture with CH2Cl2. The organic phase was washed sequentially with H2O and brine, and then dried over Na2SO4. The mixture was filtered and the filtrate was evaporated under reduced pressure to afford Compound 9a. The crude product was used in the next reaction without further purification. MS: m/z 521.3 (M+H)+.
