실험 절차

The title compound was prepared by following general procedure 1. p-Tolyl hydrazine hydrochloride (15 g, 94.55 mmol) was taken into 7% H2SO4 in 1,4-dioxane (650 mL), 1-methylazepan-4-one.HCl (15.4 g, 94.55 mmol) was added and stirred at RT for 10 min. The reaction mixture was stirred at 80° C. for 14 h. After completion of the reaction, reaction mass was slowly basified with 50% NaOH solution, extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and evaporated to dryness and purified by column chromatography (silica gel 100-200 mesh; eluent: 10% methanol-DCM) to afford 3,9-dimethyl-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole (5 g).
