실험 절차

A mixture of 2-chloro-5-methyl-pyrimidin-4-ylamine (1.2 g, 8.1 mmol), 4-bromo-1-fluoro-2-methoxy-benzene (1.8 g, 8.9 mmol), Pd2(dba)3 (0.74 g, 0.81 mmol), Xantphos (0.93 g, 1.6 mmol) and cesium carbonate (7.88 g, 24.2 mmol) were suspended in dioxane (60 mL) and heated at reflux under the argon atmosphere for 5 h. The reaction mixture was cooled to room temperature and diluted with DCM (30 mL). The mixture was filtered and the filtrate concentrated in vacuo. The residue was purified by flash chromatography on silica gel to afford the title compound (0.3 g, 14%) as a beige solid.
