Reaction Steps
A mixture of 2,4,6-trichloropyrimidine (275 mg, 1.5 mmol), 1,3-dimethyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-one (246 mg, 1 mmol), Pd(OAc)2 (20 mg), triphenylphosphine (16 mg), and 2M Na2CO3 (1 mL, 2 mmol) in THF (6.7 mL) was purged with nitrogen for 5 min, capped, and heated to 80° C. for 3 h. After the mixture was filtered through a short bed of celite, the filtrate was concentrated in vacuo and purified by silica gel column chromatography using a gradient (0 to 100%) EtOAc in DCM to afford the title compound (150 mg, 55%) as a white solid. LCMS (M+H)+=271.
