Procedure

To a solution of compound 3-[8-(2,6-difluorophenyl)-2-(methylsulfinyl)-7-oxo-5,6,7,8-tetrahydropyrimido[4,5-d]pyrimidin-4-yl]-N-(4-fluorophenyl)-4-methylbenzamide (20 mg, 0.036 mmol) in THF(3 mL) was added N,N-dibutyl-1,3-propanediamine (0.041 mL, 0.182 mmol). The resultant solution was stirred at room temperature over night. The result mixture was concentrated. CombiFlash chromatography (mobile phase DCM/DCM[90]+MeOH[7]+NH4OH[3]) provided the title compound as a white solid (16 mg, 66%). LC-MS m/z 674 (M+H)+; 1H-NMR (MeOD) δ 1.00 (t, 6H), 1.30 (m, 4H), 1.40 (m, 4H), 1.50 (m, 2H), 2.34 (s, 3H), 2.43 (m, 6H), 3.10 (m, 2H), 4.13 (s, 2H), 7.15(m, 4H), 7.53 (m, 2H), 7.72 (m, 2H), 7.82 (s, 1H), 7.98 (d, 1H).
