Reaction Steps

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]-4-methyl-N-(1-methylethyl)benzamide (36 mg, 0.072 mmol) in THF (2 mL)/CHCl3 (2 mL) were added 1-methyl-4-(4-piperidinyl)piperazine (40 mg, 0.22 mmol) and N,N-diisopropylethylamine (0.1 mL, 0.5 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 (38 mg, 85%). LC-MS m/z 619 (M+H)+; 1H-NMR (MeOD) δ 1.27 (d, 6H), 1.33 (m, 2H), 1.83 (d, 2H), 2.28 (s, 3H), 2.30 (s, 3H), 2.65 (m, 11H), 4.11 (m, 2H), 4.23 (m, 1H), 4.45 (m, 2H), 7.16 (t, 2H), 7.46 (d, 1H), 7.50 (m, 1H), 7.68 (s, 1H), 7.85 (d, 1H).
