Procedure

6-Chloropyrimidin-4-amine 7-2 (0.317 g, 2.44 mmol) and diisopropylethylamine (0.0.316 g, 2.44 mmol) were suspended in n-butanol and 1-(2-pyrrolidin-1-ylethyl)piperazine 11-1 (0.448 g, 2.44 mmol) was added. The reaction was stirred at 125° C. for 18 hours. Upon cooling the reaction was purified on a silica column (DCM:MeOH:NH4OH) to afford 11-2. 1NMR (CD3OD): 7.96 ppm (s, 1H); 5.71 ppm (s, 1H); 3.53 ppm (t, 4H); 2.69 ppm (m, 2H); 2.58 ppm (m, 10H); 1.82 ppm (m, 4H).
