Versuchsvorschrift

To a solution of 8-chloro-6-fluoro-2,3,4,5-tetrahydro-2-methyl-1H-pyrido[4,3-b]indole (300 mg, 1.26 mmol) in NMP (3.0 ml), powdered KOH (705 mg, 12.57 mmol) was added and stirred for 10 min at 25 deg C. After which 2-(trifluoromethyl)-5-vinylpyridine (435 mg, 2.5 mmol) was added slowly to the above solution and stirred for 24 h at 25 deg C. After completion of the reaction (monitored by LCMS), DM water was added to the crude and extracted with the ethylacetate. The organic layer was separated, dried and concentrated. The resulting crude was purified 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) to obtain 15 mg of 8-chloro-6-fluoro-5-(2-(6-(trifluoromethyl)pyridin-3-yl)ethyl)-2,3,4,5-tetrahydro-2-methyl-1H-pyrido[4,3-b]indole as TFA salt.
