This compound has unique chemical properties. The synthetic route is as follows.
A mixture of 1,3-dimethyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2(1H)-one (249 mg, 1 mmol), 4,6-dichloro-2-phenylpyrimidine (171 mg, 1.0 mmol), Pd(PPh3)4 (116 mg, 0.1 mmol), aqueous sodium carbonate (2.0 M, 1 mL, 2 mmol) in dioxane (5 mL) was stirred and heated at 100¡ã C. for 2 h. The reaction mixture was diluted with water and extracted with EtOAc (3*). The extracts were combined, washed with brine, dried (Na2SO4) and concentrated. The residue was purified by flash column chromatography (EA:Hex, 0-80percent) to provide the 173 mg (67percent) of the desired product as an off-white solid. 1H NMR (400 MHz, DMSO-d6) delta ppm 2.13 (s, 3 H) 3.61 (s, 3H) 7.51-7.66 (m, 4H) 8.01 (s, 1H) 8.29 (s, 1H) 8.49 (dd, J=7.83, 1.77 Hz, 2H) 8.87 (d, J=2.27 Hz, 1H). LCMS (M+H)+312.
