반응 단계

Tetra butyl ammonium chloride (0.026 g, 0.094 mmol) was taken in 15 ml, 50% aq. NaOH solution (7 ml) and stirred for 15 minutes at RT. 8-bromo-2-methyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (0.500 gm, 1.89 mmole) was added and further stirred for 10 min. at RT. 2-methyl-5-vinylpyridine (0.247 gm, 2.08 mmole) was added and reaction mixture was heated at 100° C. for 12-15 hrs. The reaction mixture was cooled at RT, extracted with ethyl acetate, dried over anhydrous sodium sulphate, concentrated and purified by Reverse Phase HPLC to get 63 mg 8-bromo-2-methyl-5-(2-(6-methylpyridin-3-yl)ethyl)-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole as TFA Salt.
