Versuchsvorschrift

A solution of 9-nitro-1,7-diphenyl-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinoline (Intermediate 3), (1.2 g, 7.06 mmol), in MeOH (100 mL) was subjected to hydrogenation reaction by the action of 10% Pd/C (120 mg) under H2 balloon at room temperature for 12 h. The mixture was filtered through Celite and freed of solvent under reduced pressure to get 1,7-diphenyl-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinolin-9-amine (Intermediate 4) as a solid, (1.08 g, 98%).
