Procedure

To a solution of compound of example 12 (0.2 g, 1.47 mmol) in water (5 mL) and ethanol (2.5 mL) was added ethyl 4-chloroacetoacetate (0.387 g, 2.35 mmol) and sodium carbonate (0.280 g, 2.64 mmol) at room temperature, and the reaction mixture was stirred for about 24 hours. Ethanol was removed under reduced pressure, and the reaction mixture was diluted with water and extracted with ethyl acetate (3×20 mL). The organic layer was dried over anhydrous sodium sulfate and concentrated to obtain the crude product, which was purified by column chromatography using silica gel and 1% methanol in chloroform to obtain the title compound.
