Procedure

To a solution of compound of example 12 (0.05 g, 0.36 mmol) in water (2 mL) and ethanol (1 mL) was added ethyl-2-chloroacetoacetate (0.096 g, 0.58 mmol) and sodium carbonate (0.070 g, 0.66 mmol) and the reaction mixture was stirred at room temperature for 26 hours. Ethanol was removed under reduced pressure, and the reaction mixture was diluted with water and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and concentrated to obtain the crude product, which was purified by column chromatography (silica gel, 1% methanol in chloroform as an eluent) to obtain the title compound.
