Versuchsvorschrift

1-[2-(Trifluoromethyl)-1H-pyrrolo[2,3-b]pyridin-5-yl]methanamine (Intermediate 5, 130 mg, 0.604 mmol), 4-chloro-6-(trifluoromethyl)pyrimidine (165 mg, 0.906 mmol) and DIPEA (0.211 mL, 1.208 mmol) in N-methyl-2-pyrrolidone (2 mL) were stirred at 150° C. for 1 hour in the microwave. The reaction mixture was diluted with ethyl acetate (25 mL) and washed with water (10 mL), brine (10 mL), water (10 mL) and brine (10 mL). The organic layer was dried (sodium sulfate), filtered and concentrated under reduced pressure to give a brown oil. This oil was dissolved in a mixture of acetonitrile and DMSO (1:1) (2.7 mL) and purified by MDAP (3 injections). Fractions containing the suspected product were combined and concentrated under reduced pressure to give the title compound as a pale brown solid (72 mg);
