Reaction Steps
Sodium acetate (0.054 g, 0.658 mmol) in water (5 mL) was added to solution of compound of Example 4 (0.18 g, 0.405 mmol) in DMF (5 mL) at 25° C. and then the reaction mixture was stirred at 80° C. for 6 h. The solvent was removed under vacuum, water (15 mL) was added and extracted using ethyl acetate (3×30 mL). Combined organic layer was washed with water (2×100 mL), brine (100 mL) and dried over anhydrous sodium sulfate. The solvent was removed under vacuum and crude product was purified by column chromatography (silica gel) to obtain the title compound (B) (1% methanol in chloroform) and compound (A) (2% methanol in chloroform).
