Reaction Steps

A mixture of 6-chloro-N4-(1,1-dimethyl-2-phenylethyl)-2,4-pyrimidinediamine (338 mg, 1.22 mmol), 2-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzonitrile (452 mg, 1.83 mmol), Pd(PPh3)4 (139 mg, 0.12 mmol) and Na2CO3 (323 mg, 3.05 mmol) in 1,4-dioxane (6 mL) and water (2 mL) was stirred and heated at 140° C. for 30 min in a Biotage Initiator microwave synthesizer. The reaction mixture was cooled to room temperature and concentrated to dryness, and the resulting residue was partitioned between EtOAc and water. The aqueous layer was extracted by EtOAc (3×50 mL), and the combined organic layers were dried over Na2SO4, filtered and concentrated to dryness. Purification by RPHPLC with CH3CN in water (0.01% ammonium hydrogen carbonate) (gradient: from 70% to 80% in 7.5 min, flow rate: 30 mL/min), afforded the title compound (210 mg) as a white solid. LC-MS (ES) m/z=362 [M+H]+.
