Reaction Steps
A mixture of 4-bromo-2-fluoro-N-methylbenzamide (900 mg, 3.9 mmol), 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrimidin-2-amine (710 mg, 3.2 mmol), tetrakis(triphenylphosphine)palladium (100 mg, 0.1 mmol) and potassium carbonate (1.3 g, 9.7 mmol) in toluene (6.0 mL) and ethanol (3.0 mL) and water (3.0 mL) was heated at 110° C. for 2 hours. After cooling to RT, the reaction mixture was quenched with water and extracted with diethyl ether. The solid was filtered and washed with water and diethyl ether to afford the desired product (720 mg).
