実験手順

4-[2-(N,N′-Di-tert-butoxycarbonylamidino)-1,2,3,4-tetrahydroisoquinolin-7-yloxymethyl]piperidine-1-carboxylic acid benzyl ester (500 mg) was hydrogenated using 7.5% palladium carbon (150 mg) in a mixture of tetrahydrofuran (5 ml) and ethanol (100 ml) at 3 atm over 3 hours. After completion of the reaction, the reaction mixture was filtered through celite, and the solvent was evaporated. The residue was dried under reduced pressure to give the title compound (815 mg).
