Procedure

Benzyl 2-((3aR*,4R*,9bR*)-1-{[(1S,2R)-2-(benzoylamino)cyclohexyl]carbonyl}-2,3,3a,4,5,9b-hexahydro-1H-pyrrolo[3,2-c]quinolin-4-yl)-1H-pyrrole-1-carboxylate (407 mg, 0.67 mmol) was dissolved in methanol (3 ml), 10% palladium on carbon (50% aqueous, 240 mg) was added, and the mixture was stirred under hydrogen atmosphere for 2 hrs. The reaction solution was filtered, and the filtrate was concentrated under reduced pressure. The obtained residue was subjected to column chromatography using silica gel (30 g), and eluted with hexane-ethyl acetate (9:1-4:1, v/v). The title compound (3aR,4R,9bR) (64 mg, 20%) was obtained as a colorless amorphous form from the first eluted fraction.
