Procedure

To a 50 mL round bottom flask, 4-(2-chloro-7-(1-methyl-1H-pyrazol-4-yl)pyrido[3,2-d]pyrimidin-4-yl)morpholine (0.1 g, 0.0003 mol), 4-(3-(2,3-difluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)ureido)-N,N-dimethyl-benzamide (0.16 g, 0.00036 mol), cesium carbonate (0.244 g, 0.00075 mol), toluene (7 mL), EtOH (7 mL), and water (3 mL) were added. The reaction mixture was degassed with nitrogen for 5-10 min. To the same reaction flask, Pd(PPh3)2Cl2 (0.0105 g, 0.000015 mol) was added and again degassed with nitrogen for 5-10 min. The reaction mixture was stirred at 75° C. for 3 h. To the cooled reaction mixture, ice cold water was added to obtain the solid. The crude product was obtained by the filtration of the solid. The crude product was purified by column chromatography using 60-120 silica gel and 4% MeOH in chloroform to isolate the product. The isolated product was washed with MeOH and filtered. The compound was further purified by prep TLC using 7% MeOH in chloroform to yield the title compound [0.02 g, 11%]. 1H NMR (400 MHz, DMSO-d6): δ 9.38 (brs, 1H), 9.09 (d, J=2.0 Hz, 1H), 9.01 (brs, 1H), 8.53 (s, 1H), 8.32 (d, J=2.0 Hz, 1H), 8.24 (s, 1H), 8.14-7.97 (m, 2H), 7.54 (d, J=8.4 Hz, 2H), 7.40 (d, J=8.4 Hz, 2H), 4.49 (brs, 4H), 3.92 (s, 3H), 3.81 (brs, 1H), 2.96 (s, 6H). LC-MS (ESI): Calculated mass: 613.2; Observed mass: 614.2 (RT: 0.63 min).
