Reaction Steps
Combine 6-chloro-5-((2,2,2-trifluoroethylamino)methyl)pyrimidin-4-amine (9.57 g, 39.78 mmol), triethylamine (5.50 mL, 2.0 eq), and dichloromethane (795 mL). Cool to 0° C. under nitrogen. Add a solution of triphosgene (11.85 g, 1.0 eq) in dichloromethane (228 mL). Stir at 0° C. for 30 min, and allow to warm to room temperature. Heat the reaction mixture to 40° C. overnight. Add aqueous sodium bicarbonate and extract with ethyl acetate. Dry the organics over anhydrous sodium sulfate, filter, and concentrate in vacuo. Purify by silica gel chromatography, eluting with 9:1 dichloromethane:methanol, to give the title compound (4.50 g, 42%). 1H NMR (400 MHz, DMSO-d6) δ 10.83 (s, 1H), 8.41 (s, 1H), 4.20 (m, 2H), 3.25 (s, 2H).
