実験手順

To a mixture of methyl 7-bromo-2,3-dihydro-1-benzoxepine-4-carboxylate (0.57 g), 3,4-methlenedioxyphenyl borate (0.47 g) and sodium carbonate (0.42 g) were added water (2 ml) and 1,2-dimethoxyethane (12 ml). Under argon atmosphere, the mixture was stirred at room temperature for 30 minutes, and to the mixture was added tetrakistriphenylphosphinepalladium (0.16 g). The mixture was stirred at 80° C. for 14 hours and extracted with ethyl acetate. The organic layer was washed with water and saturated sodium chloride solution and dried with anhydrous magnesium sulfate. Under reduced pressure, the solvent was evaporated, and the residue was purified with silica gel column (ethyl acetate/hexane) to give methyl 7-(3,4-methlenedioxyphenyl)-2,3-dihydro-1-benzoxepine-4-carboxylate (0.43 g).
