Procedure

Compound 186 (300 mg, 1.11 mmol) was dissolved in pyridine (3.7 mL), and acetyl chloride (0.130 mL, 1.89 mmol) and N,N-dimethylaminopyridine (6.75 mg, 0.0553 mmol) were added thereto, followed by stirring at room temperature for 3 hours. The reaction mixture was concentrated under reduced pressure, and the resulting residue was purified through silica gel column chromatography (hexane:ethyl acetate=2:1) to afford the entitled Compound 188 (233 mg, 67%) as a pale yellow solid.
