Reaction Steps

2,4-dichloropyrimidine-5-carbonitrile (E. F. Godefroi, J. Org. Chem., 1962, 27(6), 2264-6) (0.10 g, 0.57 mmol), 2-amino-2-methyl-N-(2,2,2-trifluoroethyl)propanamide. 1TFA (Meinke, Peter T.; Shih, Thomas L.; Fisher, Michael H., U.S. Pat. No. 6,221,894 B1) (0.171 g, 1.14 mmol) and DIPEA (0.39 mL, 2.29 mmol) were combined in anhydrous THF (5 mL) in a sealed tube and heated to 90° C. for 18 hours, before cooling to room temperature. The solvent was evaporated in vacuo and the residue purified by flash chromatography (40 g SiO2, pentane/ethyl acetate, 30-70% over 14 column volumes) to afford the title compound as a colorless waxy solid (0.036 g, 19.7%).
