실험 절차

5-chloro-1-(2,6-difluorophenyl)-7-(methylthio)-3,4-dihydropyrimido[4,5-d]pyrimidin-2(1H)-one (0.102 g, 0.298 mmol), N,N,4-trimethyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzamide from above, (0.129 g, 0.447 mmol), and K2CO3 (0.123 g, 0.894 mmol), were taken up in dioxane (6 mL) and water (1.2 mL). The mixture was degassed with argon for 30 min and tetrakis(triphenyl-phosphine)palladium(0) (0.026 g, 0.022 mmol) was added. The mixture was then heated under argon at 95°C. for 18 h. The solvents were pumped off, and after aqueous workup, the crude material was flashed on silica gel (15 g), eluted with a EtOAc/CH2Cl2 gradient to give the title compound as a white amorphous solid. mp 144-147° C. LC-MS m/z 470 (M+H)+, 2.02 min (ret time).
