To this mixture the solution of 400 mg of 6-(trifluoromethyl)pyridin-2-amine (2.467 mmol) and 379 μl of triethylamine (5.43 mmol) in 9.7 ml DCM was slowly added over 60 minutes at 0° C., and stirring was continued for an additional 60 minutes at room temperature. 550 mg of 6-bromoquinolin-4-amine (2.467 mmol) and 379 μl of triethylamine (5.43 mmol) were suspended in 9.7 ml and subsequently slowly added to the reaction mixture at RT, which became a clear solution after 45 minutes. After stirring over night the reaction mixture was poured into ice water and stirred for 2 h. The precipitation formed was filtered off and dried in vacuum for 24 h. 810 mg of the desired product were obtained as an off white powder (yield: 80%). The quite pure raw material was used without further purification in the next step.
