Reaction Steps

To a solution of methyl acetoacetate (3 ml) in acetone (30 ml) were sequentially added potassium carbonate (11.54 g) and 1,2-dibromoethane (2.4 ml) at room temperature, and the mixture was stirred at 65° C. for 17 hours. This reaction mixture was filtered, the filtrate was concentrated under reduced pressure, and the resulting residue was purified by silica gel column chromatography (eluent: n-hexane/ethyl acetate=10/1) to give the titled compound (2.17 g).
