Reaction Steps

A mixture of 2-chloro-5-methylpyrimidin-4-amine (670 mg, 4.7 mmol), 1-tert-butyl-3-bromobenzene (1.5 g, 7 mmol), Pd2(dba)3 (366 mg, 0.4 mmol). Xantphos (695 mg, 1.2 mmol) and cesium carbonate (6.2 g, 19 mmol) was suspended in dioxane (150 mL) and heated at reflux under the argon atmosphere for 20 h. The mixture was filtered and the filtrate concentrated in vacuo. The residue was dissolved in EtOAc (10 mL) and added hexanes (100 mL). The solid was collected by filtration and washed with hexanes to afford the crude title compound (1.2 g, 99%) as a yellow solid.
