Procedure

Diiodobutane (17.1 g, 55 mmol), sodium carbonate (35 g, 330 mmol), ethylbenzoylacetate (10.6 g, 55 mmol) and dimethylformamide (170 ml) were mixed and the mixture was stirred at 55 to 60° C. overnight. The mixture after completion of reaction was poured into ice water and the mixture was extracted twice with ethyl acetate (100 ml). The extract was dried over sodium sulfate, and after concentration, purified by silica gel column chromatography (hexane:ethyl acetate=9:1) to give the title compound (7.9 g, 58%) as a colorless oil.
