Reaction Steps
Ethyl acetoacetate (37.4 mL, 294 mmol) was added at 0° C. to a suspension of sodium hydride (65%, 10.8 g) in THF (600 mL), and the mixture was stirred at 0° C. for 30 minutes. It was added dropwise at 0° C. to a solution of 1-bromomethyl-2-fluoro-3-nitrobenzene (compound 1a-1) (68.7 g, 294 mmol) in THF (400 mL), and the reaction mixture was stirred at room temperature overnight. The reaction mixture was then poured into 0.5N hydrochloric acid and extracted with ethyl acetate. The organic extract was washed with saturated saline and dried over magnesium sulfate. A crude product was obtained by vacuum concentration, and purified by column chromatography (ethyl acetate:hexane=1:3) to yield the title compound (52.2 g, 63%) as a yellow oil.
