Reaction Steps

A mixture of N-(6-chloropyrimidin-4-yl)-2,6-dichlorobenzamide (302 mg, 1.0 mmol), ethyl 4-aminobenzoate (0.33 g, 2.0 mmol), Pd2(dba)3 (0.1 mmole, 92 mg), 4,5-Bis(diphenylphosphino)-9,9-dimethylxanthene (0.15 mmol, 87 mg) and cesium carbonate (2.0 mmoles; 652 mg) in a microwave tube was evacuated, back-filled with N2 (2×). 1,4-Dioxane (10 mL) was then added. The tube was sealed, and heated at 130° C. in microwave for 15 min. The mixture was filtered through Celite using EtOAc to rinse. The combined filtrates were concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (0-50% EtOAc/hexane) to afford ethyl 4-(6-(2,6-dichlorobenzamido)pyrimidin-4-ylamino)benzoate as an off-white solid (0.279 g, yield: 65%). LCMS (ESI) m/z: 431.0 [M+H+].
