실험 절차

The title compound was prepared by following general procedure 7. 3,9-Dimethyl-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole (100 mg, 0.47 mmol), was taken into DMF. CuI (9 mg, 0.046 mmol), L-proline (11 mg, 0.093 mmol), K3PO4 (198 mg, 0.93 mmol) were added to the solution and stirred for 10 min. at RT. 2-Chloro-1-(piperidin-1-yl)ethanone (91 mg, 0.56 mmol) was added dropwise. The reaction mixture was heated at 90° C. for 12 h. After completion of reaction, the reaction mixture was filtered through Celite. DMF was evaporated under reduced pressure and then extracted with ethyl acetate. The organic layer was dried over Na2SO4, and concentrated under reduced pressure to obtain 14 mg of 2-(3,9-dimethyl-2,3,4,5-tetrahydroazepino[4,5-b]indol-6(1H)-yl)-1-(piperidin-1-yl)ethanone as the TFA salt after purification by reverse-phase chromatography (C-18, 500 mm×50 mm, Mobile Phase A=0.05% TFA in water, B=0.05% TFA in acetonitrile, Gradient: 10% B to 80% B in 30 min., injection vol. 5 mL).
