Procedure
6-Chloropyrimidin-4-amine 7-2 (0.3 g, 2.32 mmol) and diisopropylethylamine (0.30 g, 2.32 mmol) were suspended in n-butanol and then 1-(2-methoxyethyl)piperazine 5-2 (0.334 g, 2.32 mmol) was added. The reaction was stirred at 125° C. for 18 hours. The butanol was removed under reduced pressure, diluted with DCM and loaded onto a silica column eluted with DCM (100 mL), DCM:MeOH (99:4) and then DCM:MeOH:NH4OH (9:1:0.1). The product 5-3 was isolated after evaporation. 1H-NMR (DMSO): 7.95 ppm (s, 1H); 6.23 ppm (s, 2H); 5.59 ppm (s, 1H); 3.43 ppm (m, 4H); 3.33 ppm (m, 2H); 3.25 ppm (s, 3H); 2.59 ppm (m, 2H); 2.54 ppm (m, 4H).
