Reaction Steps

2,8-dimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (0.15 g, 0.75 mmole), 3-(trifluoromethyl)-5-vinylpyridine (0.13 g, 0.75 mmole) and, tetra butyl ammonium chloride (2 mg, 0.0375 mmole) were charged in 5 ml, 50% aqueous NaOH. The reaction mixture at 100° C. for 8 hrs. The reaction mass was cool at RT, added 5 ml water and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulphate, concentrated and purified by Prep HPLC to get 2,8-dimethyl-5-(2-(5-(trifluoromethyl) pyridin-3-yl)ethyl)-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (35 mg).
