To a pressure bottle charged with 3-ethyl-7-nitro-3,4-dihydroisoquinoline (3.6 g, 17 mmols) dissolved in methanol (100 ml) and saturated isopropanol-HCl (20 ml) was added 10% Pd--C (250 mg), and the reaction hydrogenated for 1 h. The catalyst was removed by filtration and the solvent evaporated to yield 3-ethyl-1,2,3,4-tetrahydroisoquinolin-7-amine dihydrochloride (4.3 g).
