実験手順

To a mixture of N-{3-[2-(2-aminopyridin-4-yl)ethyl]phenyl}-2-chloro-5-fluoropyrimidin-4-amine dihydrochloride (35.0 mg, 0.084 mmol) and triethylamine (0.035 mL, 0.25 mmol) in a mixed solvent of 1,4-dioxane (0.70 mL) and N,N-dimethylformamide (0.70 mL) were added (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (5.8 mg, 0.01 mmol), palladium acetate (2.3 mg, 0.01 mmol) and cesium carbonate (54.7 mg, 0.17 mmol). The mixture was degassed by bubbling N2 through the solution. The sealed tube was then microwaved at 160° C. for 30 min. The reaction mixture was diluted with THF/MeOH, filtered and concentrated to give the residue, which was purified by silica gel column chromatography to provide the desired product as a white powder (7.8 mg, 30%). LCMS for C17H15FN5 (M+H)+: m/z=308.1. 1H NMR (400 MHz, CD3OD): δ 8.09 (d, J=5.2 Hz, 1H), 8.00 (s, 1H), 7.96 (d, J=4.0 Hz, 1H), 7.81 (d, J=1.6 Hz, 1H), 7.31 (m, 1H), 7.04 (m, 2H), 6.91 (m, 1H).
