実験手順: 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, 0.46 mmol), was taken into DMF. To the above solution CuI (9 mg, 0.046 mmol), L-proline (11 mg, 0.093 mmol), K3PO4 (198 mg, 0.93 mmol) were added and stirred for 10 min. at RT. 2-Chloro-N-(4-fluorophenyl)acetamide (105 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 104 mg of 2-(3,9-dimethyl-2,3,4,5-tetrahydroazepino[4,5-b]indol-6(1H)-yl)-N-(4-fluorophenyl)acetamide 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). The title compound was prepared 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 extracted with ethyl acetate The organic layer was dried over Na2SO4 concentrated under reduced pressure
