実験手順
A mixture of 2-(benzo[1,3]dioxol-5-ylmethyl)-6-bromo-1-oxo-4-phenyl-1,2-dihydroisoquinoline-3-carboxylic acid methyl ester (300 mg), zinc cyanide (50 mg), tetrakis(triphenylphosphine)palladium(0) (35 mg) and 1-methyl-2-pyrrolidone (3 ml) was stirred at 100° C. for 2 hrs. under an argon atmosphere. Water was added to the reaction mixture, and the mixture was extracted with a mixture of ethyl acetate and THF. The organic layer was washed with aqueous ammonia, water and saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (ethyl acetate). The solvent was evaporated under reduced pressure, and the obtained crystals were washed with a mixture of ethyl acetate and diethyl ether to give the title compound (210 mg).
