To a solution of N,N-Dimethylpropionamide (0.202 g, 2.0 mmol) in CHCl3 (2 mL) was added phosphorous oxychloride (POCl3, 0.066 g, 0.43 mmol) and the mixture was agitated on an orbital shaker at room temperature for 1 h. Triethylamine (0.22 g, 2.2 mmol) and 5-fluoro-2-(4-fluorobenzyloxy)pyrimidin-4-ylamine (0.10 g, 0.40 mmol) were added, and the mixture was agitated at 50° C. for 3 h, cooled to room temperature, partitioned between chloroform and water, the phases separated, and the organics evaporated under reduced pressure. Purification by reverse phase chromatography afforded the title compound (0.042 g, 31% yield) as a yellow oil: 1H NMR (300 MHz, CDCl3) δ 8.87 (s, 1H), 8.04 (d, J=2.5 Hz, 1H), 7.46-7.40 (m, 2H), 7.07-6.99 (m, 2H), 5.30 (s, 2H), 3.13 (s, 6H), 2.55 (q, J=7.7 Hz, 2H), 1.15 (t, J=7.7 Hz, 3H); HPLC-MS (ESI) m/z 321 (M+H)+.
