Versuchsvorschrift

6-Chloropyrimidin-4-amine 7-2 (0.149 g, 1.15 mmol) and diisopropylethylamine (0.446 g, 3.45 mmol) were suspended in n-butanol. 2,2,2-Trifluoro-N-piperidin-3-ylacetamide 9-3 (0.226 g, 1.15 mmol) was then added. The reaction was stirred at 170° C. for 24 hours. The butanol was then removed under reduced pressure and the product was purified on a silica column eluted with DCM:MeOH:NH4OH (95:5:0.5). 1H-NMR (CD3OD): 8.06 ppm (s, 1H); 5.82 ppm (s, 1H); 4.27 ppm (d, 1H); 4.15 ppm (d, 1H); 3.85 ppm (m, 1H); 3.73 ppm (p, 3H); 3.23 ppm (q, 3H); 3.08 ppm (dd, 2H); 2.13 ppm (m, 1H); 1.85 ppm (m, 1H); 1.71 ppm (m, 1H); 1.62 ppm (m, 1H).
