実験手順

A suspension of (2-bromo-4-methoxyphenyl)[4-(2-piperidin-1-ylethoxy)phenyl]methanone (570 mg), (6-methoxy-3,4-dihydronaphthalen-2-yl)trimethyltin (542 mg), tetrakis(triphenylphosphine)palladium(0) (80 mg) and copper(I) iodide (25 mg) in toluene (10 ml) was stirred for 5 hours at 100° C. under a nitrogen atmosphere. Ethyl acetate was added thereto, the insoluble material was removed by filtration, the solvent was evaporated in vacuo, and the resulting residue was purified by NH silica gel column chromatography (hexane-ethyl acetate system) to provide the title compound (263 mg).
