Reaction Steps

To a magnetically stirred solution of 5-fluoro-2-(4-fluorobenzyloxy)pyrimidin-4-ylamine (1.00 g, 4.2 mmol) in N,N-dimethylformamide (DMF, 20 mL) was added N,N-dimethylformamide dimethyl acetal (0.55 g, 4.6 mmol) and stirring was continued 16 h at RT. The solution was poured into 100 mL of ice water, whereupon a white precipitate was produced. The mixture was cooled at 0° C. for 1 h and then filtered to produce the title compound (1.10 g, 89%) as a white solid: mp 113-115° C.; 1H NMR (CDCl3) δ 8.65 (s, 1H), 8.04 (d, J=2.6 Hz, 1H), 7.46-7.40 (m, 2H), 7.07-6.98 (m, 2H), 5.30 (s, 2H), 3.17 (s, 3H), 3.16 (s, 3H); MS (ESI) m/z 292 (M+H)+. Anal. Calcd for C14H14F2N4O: C, 57.53; H, 4.83; N, 19.17. Found: C, 57.67; H, 4.84; N, 19.09.
