Participants

Reaction Steps

6-[4-(2-Pyrrolidin-1-ylethyl)piperazin-1-yl]pyrimidin-4-amine 11-2 (0.35 g, 1.27 mmol), sodium hydride (0.101 g, 2.53 mmol) and 2-chloro-1,3-thiazole-5-carbonitrile 2-2 (0.183 g, 1.27 mmol) were treated as in Scheme 4 above. The product was purified on a C18 preparative column and isolated via lyophilization. Hi-Res MS: calc: 385.1921 found: 385.1918. 1NMR (DMSO): 12.1 ppm (s, 1H); 8.46 ppm (s, 1H); 8.27 ppm (s, 1H); 6.27 ppm (s, 1H); 3.63 ppm (m, 6H); 3.35 ppm (m, 4H); 2.76 ppm (m, 6H); 1.96 ppm (s, 4H).
