Reaction Steps

1M HCl (15 mL) was added to 5-fluoro-4-(2-fluoropyridin-4-yl)-N-(tetrahydro-2H-pyran-4-yl)pyrimidin-2-amine (0.26 g, 0.89 mmol). The suspension was heated at reflux. After 2.5 hours, the suspension was neutralized with NaHCO3, and the solid was collected by vacuum filtration. This was suspended in MeOH and evaporated to yield 4-(5-fluoro-2-((tetrahydro-2H-pyran-4-yl)amino)pyrimidin-4-yl)pyridin-2(1H)-one (0.25 g, 0.86 mmol, 97% yield). 1H NMR (400 MHz, (CD3)2SO) δ 11.80 (br s, 1H), 8.48 (d, 1H), 7.52 (d, 1H), 7.40 (d, 1H), 6.83 (br s, 1H), 6.65-6.61 (m, 1H), 3.90-3.84 (m, 3H), 3.43-3.36 (m, 2H), 1.88-1.81 (m, 2H), 1.57-1.46 (m, 2H); m/z (APCI-pos) M+1=291.1.
