Procedure

To 3-[2-[(3-chloropropyl)amino]-8-(2,6-difluorophenyl)-7-oxo-5,6,7,8-tetrahydropyrimido[4,5-d]pyrimidin-4-yl]-4-methyl-N-propylbenzamide (265 mg, 0.50 mmol) in DMF (10 mL) was added ethylamine (1.25 mL, 2.0 M in THF, 2.5 mmol) and potassium carbonate (0.276 g, 2.0 mmol). The mixture was heated at 50° C. for about 20 hours, then at 80° C. for about 4 hours. The mixture was diluted with EtOAc (50 mL), washed with H2O (30 mL+15 mL×2) and brine (20 mL). The organic layers were collected and concentrated. Flash chromatograph afforded the title compound (134 mg, 50%). LC-MS m/z 538 (M+H)+; 1H-NMR (MeOD) δ 0.96-1.02 (m, 6H), 1.61-1.72 (m, 2H), 1.85-1.96 (m, 2H), 2.30 (s, 3H), 3.07 (q, J=7.11 Hz, 2H), 3.19-3.29 (m, 3H), 3.33-3.40 (m, 3H), 3.83 (d, 1H), 3.90 (d, 1H), 6.83-6.99 (m, 3H), 7.51 (d, J=8.03 Hz, 1H), 7.69 (d, J=1.76 Hz, 1H), 7.87 (dd, J=7.91, 1.88 Hz, 1H).
