In methanol (50 ml), 2-tert-butoxycarbonyl-6-trifluoromethanesulfonyloxy-1,2,3,4-tetrahydroisoquinoline (1.34 g) was dissolved, followed by the addition of triethylamine (0.73 ml), palladium (II) acetate (40 mg) and 1,3-(diphenylphosphino)propane (145 mg). The resulting mixture was stirred overnight at 70° C. under a carbon monoxide gas stream. After the reaction mixture was concentrated under reduced pressure, the residue was purified by chromatography on a silica gel column (hexane:ethyl acetate=15:1), whereby the title compound (665 mg, 65%) was obtained.
