A mixture of 4-chloro-6-(2-{4-[3-(methyloxy)phenyl]-1H-imidazol-2-yl}-4-morpholinyl)-2-pyrimidinamine (770 mg, 1.991 mmol), 2-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzonitrile (590 mg, 2.389 mmol), Na2CO3 (464 mg, 4.38 mmol) and Pd(PPh3)4 (138 mg, 0.119 mmol) in 1,4-dioxane (8 mL) and water (2 mL) was heated at 140° C. under microwave condition with stirring for 1 hour. The mixture was filtered, washing with EtOAc (100 mL), and concentrated to afford the crude title compounde (1.0 g) as a grey oil. This material was combined with another sample of the title compound (100 mg). The combined material was purified by silica gel chromatography, eluting with EtOAc in PE from 50% to 80% to afford the title compound (760 mg) as a brown solid. LC-MS (ES) m/z=472 [M+H]+.
