Reaction Steps

To a suspension of LiAlH4 in 1,4-dioxane (26 mL) was added 5,6,8,9,10,11-hexahydro-4H,12H-azepino[3′,4′:4,5]pyrrolo[3,2,1-ij]quinolin-12-one (300 mg, 1.25 mmol) under N2 at 20° C. The reaction mixture was refluxed for 15 h. The reaction mixture was cooled in an ice bath and added successively with H2O (0.3 mL), 15% NaOH (0.3 mL) and H2O (0.8 mL). The mixture was stirred for 1 h at 20° C. then filtered. The filtrate was concentrated in vacuo. The residue was dissolved in dilute AcOH and washed with Et2O. The aqueous solution was basified with 1N NaOH. A white solid was precipitated and filtered to yield 5,6,9,10,11,12-hexahydro-4H,8H-azepino[3′,4′:4,5]pyrrolo[3,2,1-ij]quinoline (270 mg, 95%).
