Reaction Steps

The title compound was synthesized by referring to Tetrahedron Lett., 1993, 34 (21), 3421. A suspension of 7-benzyloxy-3-bromo-1,2-dihydronaphthalene (38 g), 4-bromo-3-nitroanisole (59 g), dichlorobis(triphenylphosphine)palladium (II) (4.5 g) and copper (32 g) in dimethyl sulfoxide (400 ml) was stirred under a nitrogen atmosphere at 120° C. for 1 hour. Ethyl acetate and water was added thereto, the solution was filtered through celite pad, extracted with ethyl acetate, then sequentially washed with aqueous ammonia, water and brine, dried over anhydrous magnesium sulfate, and then the solvent was evaporated in vacuo. The residue was purified by silica gel column chromatography (hexane-ethyl acetate system) to provide the title compound (19 g).
