実験手順: A mixture of 2-chloro-5-methyl-pyrimidin-4-ylamine (0.18 g, 5.9 mmol), 1-bromo-2-methyl-3-trifluoromethyl-benzene (0.33 g, 1.4 mmol), Pd2(dba)3 (0.12 g, 0.13 mmol), Xantphos (0.15 g, 0.25 mmol) and cesium carbonate (1.23 g, 3.8 mmol) were suspended in dioxane (8 mL) microwaved at 160° C. for 18 min. Reaction vessel was then centrifuged down and decanted. Solvents then evaporated and resulting residue was purified by flash chromatography on silica gel to afford title compound as white solids (0.095 g, 25%). microwaved at 160° C. for 18 min Reaction vessel decanted Solvents then evaporated resulting residue was purified by flash chromatography on silica gel

実験手順: To a solution of 1-bromo-2-methyl-3-(trifluoromethyl)benzene (CXXVII) (5.7 g, 23.86 mmol) in CCl4 (50 mL) was added NBS (4.24 g, 23.86 mmol) and a catalytic amount of benzoyl peroxide. The reaction mixture was gently refluxed for 1 h. The reaction mixture was cooled to room temperature and the precipitate was removed by filtration. The solution was concentrated under reduced pressure and the crude product was dissolved in hexane and additional precipitate was removed by filtration. The filtrate was concentrated to dryness to give 1-bromo-2-(bromomethyl)-3-(trifluoromethyl)benzene (CXXVIII) as an orange oil (7.51 g, 23.62 mmol). 1H NMR (DMSO-d6) δ ppm 4.73 (s, 2H), 7.4 (dd, J=8 Hz, J=8 Hz, 1H), 7.80 (d, J=8 Hz, 1H), 8.02 (d, J=8 Hz, 1H); 19F NMR (DMSO-d6) δ ppm −57.85 (s, 3F). The crude product was used without further purification for step 2. The reaction mixture was gently refluxed for 1 h the precipitate was removed by filtration The solution was concentrated under reduced pressure the crude product was dissolved in hexane additional precipitate was removed by filtration The filtrate was concentrated to dryness
