Reaction Steps

To a solution of 4-bromo-1-ethyl-2-nitro-benzene (8.7 g, 0.037 mol) in THF at −40° C. was added vinylmagnesium bromide (132 ml, 0.132 mol) dropwise, and the mixture was stirred at −40° C. for a further 2 h. The reaction mixture was diluted with water, extracted with EtOAc, dried over Na2SO4 and concentrated. The crude product was purified by silica gel column chromatography to afford the title compound (1.35 g, 16%).
