Reaction Steps

The title compound was prepared by following general procedure 4. To a solution of 9-chloro-3-methyl-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole (150 mg, 0.6 mmol) in 50% aq. NaOH solution (7 mL), tetra n-butyl ammonium chloride (9 mg, 0.03 mmol) was added followed by 2-vinylpyridine (74 mg, 0.7 mmol) The reaction mixture was heated at 80° C. for 14 h. After completion of reaction, the reaction mixture was diluted with water, extracted with ethyl acetate; the organic layer was dried over Na2SO4, and concentrated under reduced pressure. The crude product was purified by reverse phase chromatography to afford 80 mg of 9-chloro-3-methyl-6-(2-(pyridin-2-yl)ethyl)-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole as the TFA salt.
