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 2-methoxy-N-(2-methoxyethyl)ethanamine 6-1 (0.31 g, 2.32 mmol) was added. The reaction was stirred at 180° C. for 24 hours. The solvent was removed under reduced pressure and the product 6-2 was purified on a silica column. 1H-NMR (DMSO): 7.91 ppm (s, 1H); 6.10 ppm (2H); 5.51 ppm (s, 1H); 3.45 ppm (m, 4H); 3.45 ppm (m, 4H); 3.25 ppm (s, 6H).
