Reaction Conditions

Temperature	140 °C

Reaction Steps

4-Chloro-6-[(3R)-3-ethyl-4-morpholinyl]-N-methyl-2-pyrimidinamine (250 mg, 0.974 mmol) was added to a 20 mL microwave vial, followed by (4-cyano-3,5-difluorophenyl)boronic acid (356 mg, 1.948 mmol), PdCl2(dppf).CH2Cl2 adduct (39.8 mg, 0.049 mmol), 2M K2CO3 (1.461 mL, 2.92 mmol) and 1,4-dioxane (4 mL). The mixture was heated to 140° C. for 10 minutes. The reaction mixture was filtered through a silica plug and washed with EtOAc (3×). The filtrate was then washed with H2O (2×) and the organic layer was dried over Na2SO4 and concentrated to afford the title compound (453 mg) as a brown oil. LC-MS (ES) m/z=360 [M+H]+.
