Reaction Steps

To a mixture of sodium hydride (33.6 mg, 0.84 mmol) in 2 mL of dimethylsulfide is added N,N-Dimethylaminopropan-1-ol (99 μL, 0.84 mmol) slowly. After 30 minutes, 2-(5-aminopyridin-2-yl)-6-chloro-N-(2,2,2-trifluoroethyl)-5-(2,4,6-trifluorophenyl)pyrimidin-4-amine (100 mg, from Step A) is added and the resulting reaction mixture is heated at 60° C. for 4 h. The reaction mixture is cooled to room temperature, and diluted with ethyl acetate. The organic layer is washed with water and then with saturated sodium chloride solution, dried over magnesium sulfate, filtered, concentrated and dried under reduced pressure to yield 2-(5-aminopyridin-2-yl)-6-chloro-5-{4-[3-(dimethylamino)propoxy]-2,6-difluorophenyl}-N-(2,2,2-trifluoroethyl)pyrimidin-4-amine as a yellow semi-solid (60 mg). MS: m/z 517.3 (M+H). This product was used in the next step without further purification.
