6-[4-(2-morpholin-4-ylethyl)piperazin-1-yl]pyrimidin-4-amine 7-4 (1.5 g, 5.13 mmol), sodium hydride (0.41 g, 10.26 mmol) and 2-chloro-1,3-thiazole-5-carbonitrile 2-2 (0.74 g, 5.13 mmol) were treated as in Scheme 4 above. The product was purified on a silica column eluted with DCM:MeOH:NH4OH (95:5:0.5 and 9:1:0.1) and isolated directly from the appropriate fractions after they were concentrated and the residue was suspended in methanol and filtered. 1H-NMR (CDCl3): 9.27 ppm (s, 1H); 8.45 ppm (s, 1H); 7.90 ppm (s, 1H); 5.87 ppm (s, 1H); 3.72 ppm (m, 4H); 3.65 ppm (s, 4H); 2.57 ppm (m, 8H); 2.50 ppm (s, 4H).
