Procedure

The title compound was prepared by following general procedure 7. 9-Chloro-3-methyl-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole (100 mg, 0.43 mmol), was taken into DMF. CuI (8 mg, 0.043 mmol), L-proline (10 mg, 0.086 mmol), K3PO4 (183 mg, 0.85 mmol) were added to the solution and stirred for 10 min. at RT. 2-Chloro-1-(piperazin-1-yl)ethanone (0.135 mg, 0.51 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. The crude compound was purified by column chromatography to gives 35 mg, and then the compound was stirred in ethanolic HCl to give the HCl salt of 2-(9-chloro-3-methyl-2,3,4,5-tetrahydroazepino[4,5-b]indol-6(1H)-yl)-1-(piperazin-1-yl)ethanone.
