Procedure

The title compound was prepared by following general procedure 4. 9-Chloro-3-methyl-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole (100 mg, 0.42 mmol), tetra n-butyl ammonium chloride (6 mg, 0.025 mmol), 4-vinylpyridine (53 mg, 0.51 mmol) were taken into 50% NaOH (3 mL). The reaction mixture was heated overnight at 110° C. The reaction was monitored by TLC. After completion of reaction, the reaction mixture was extracted with ethyl acetate and water, the organic layer was dried over Na2SO4, and concentrated under reduced pressure to obtain 40 mg of 9-chloro-3-methyl-6-(2-(pyridin-4-yl)ethyl)-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole 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).
