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. 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-N-isopropylacetamide (76 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 7 mg of 2-(3,9-dimethyl-2,3,4,5-tetrahydroazepino[4,5-b]indol-6(1H)-yl)-N-isopropylacetamide 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

実験手順: 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 (9 mg, 0.086 mmol), K3PO4 (183 mg, 0.86 mmol) was added to the solution and stirred for 10 min. at RT. 2-Chloro-N-isopropylacetamide (65 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 the residue was extracted with ethyl acetate. The organic layer was dried over Na2SO4, and concentrated under reduced pressure to obtain 40 mg of 2-(9-chloro-3-methyl-2,3,4,5-tetrahydroazepino[4,5-b]indol-6(1H)-yl)-N-isopropylacetamide 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).

実験手順: To a suspension of 2-(2-isopropyl-5-methyl-2H-[1,2,4]triazol-3-yl)-8-piperidin-4-yl-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulene hydrochloride (150 mg, 0.35 mmol) in DCM (2 mL) was added triethylamine (107 μL, 0.77 mmol). The resultant mixture was stirred for 10 minutes before the addition of 2-chloro-N-isopropyl-acetamide (52 mg, 0.38 mmol) and tetrabutylammonium iodide (13 mg, 0.04 mmol). The reaction was stirred at RT for 4 days before the reaction was washed with sodium hydrogen carbonate solution (sat. aq.). The aqueous phase was extracted with 10% MeOH in DCM (×3) and the combined organic layers dried (Na2SO4) then concentrated in vacuo. The resultant residue was purified by flash column chromatography (SiO2, gradient 0-10% MeOH in DCM) affording 277 (88 mg, 0.18 mmol, 51%).
