Reaction Steps

A mixture of (1S,7S)-1,7-dimethyl-9-nitro-1,7-diphenyl-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinoline (7), (2 g, 5 mmol), in THF (60 mL) was subjected to hydrogenation reaction by the action of 10% Pd/C (200 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 (1S,7S)-1,7-dimethyl-1,7-diphenyl-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinolin-9-amine (9) as a solid, (1.5 g, 100%) on the basis of recovered starting material (7), (390 mg).
