Reaction Steps

A mixture of 2-(4-bromo-2-fluorophenyl)-2-hydroxy-N-methylacetamide (0.4 mmol), 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrimidin-2-amine (0.11 g, 0.48 mmol), tetrakis(triphenylphosphine)palladium (0.01 g, 0.01 mmol) and potassium carbonate (0.16 g, 1.2 mmol) in toluene (0.6 mL) and 1,4-dioxane (0.6 mL) was heated at 100° C. for 1.5 h. After cooling to RT, the mixture was filtered through a pad of silica gel, washed with 10% methanol in dichloromethane. The filtrate was concentrated under reduced pressure and the residue purified by chromatography on silica gel with 10% methanol in dichloromethane to afford the desired product. LCMS: (M+H)=277.0.
