Reaction Steps

To a solution of 2,4,6-trichloro-5-fluoropyrimidine (2.01 g) in absolute ethanol (50 mL) was added DIEPA (4.4 mL) and 5-methoxy-1H-pyrazol-3-amine (2.24 g). The resulting solution was stirred at room temperature for over night. The solvent was removed by reduced pressure and the residue was purified by Gilson (10-50% MeCN/H2O, 15 minutes) to give the titled compound 2,6-dichloro-5-fluoro-N-(5-methoxy-1H-pyrazol-3-yl)pyrimidin-4-amine as solid (0.776 g). m/z 278. A mixture of morpholine (0.256 mL), 2,6-dichloro-5-fluoro-N-(5-methoxy-1H-pyrazol-3-yl)pyrimidin-4-amine (776 mg) and DIPEA (0.742 ml) in n-butanol (14.0 ml) was heated at 90° C. for 5 hours. The solvent was removed under reduced pressure and the residue was purified by Gilson (10-50% MeCN/H2O, 15 minutes) to give the titled compound as solid (310 mg). 1H NMR 9.80 (s, 1H) 5.66 (s, 1H) 3.77 (s, 3H) 3.64-3.71 (m, 4H) 3.53-3.64 (m, 4H); m/z 329.
