Reaction Steps

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), palladium(II) acetate (7 mg), 1,1′-bis(diphenylphosphino)ferrocene (17 mg), triethylamine (0.22 ml), DMF (10 ml) and methanol (10 ml) was stirred at 100° C. for 6 hrs. under 5 atm carbon monoxide. The reaction mixture was concentrated, and water was added to the residue. The mixture was extracted with ethyl acetate. The organic layer was washed with 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) and the obtained crystals were washed with diisopropyl ether to give the title compound (250 mg).
