Reaction Conditions

Reaction Steps

To N,N-dimethylformamide (400 ml) were added ethyl benzoylacetate (25.1 g, 0.13 mol), 1,4-diiodobutane (40.47 g) (0.13 g) and anhydrous sodium carbonate (82.7 g, 0.78 mol) and the mixture was stirred at 60° C. for 15.5 h. The reaction mixture was poured into 1 L of water and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dehydrated over anhydrous sodium sulfate and concentrated. A red residual solution (33.5 g) was purified by silica gel column chromatography (ethyl acetate/hexane=1/4) to give the title compound (24.67 g) as a colorless oil (yield 77%).
