実験手順

A solution of 1-bromo-4-fluoro-2-nitrobenzene (3.6 g, 16.4 mmol) in THF (100 mL) was added to a solution of 1 M vinylmagnesium bromide in THF (100 mL, 100 mmol) and DME (100 mL) at −78° C. (bath temp). The reaction was stirred at −78° C. for 4 h, and saturated aqueous NH4Cl was added. The layers were separated, and the organic layer was evaporated. The crude product was purified flash chromatography, giving 2 g (57%) of the title compound.
