실험 절차

To a suspension of 4-[8-(4-methanesulfonyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-ylamino]-phenol (100.0 mg, 0.2629 mmol) and triethylamine (55.0 L, 0.395 mmol) in acetonitrile (1 mL) was added 1,1,2,2,3,3,4,4,4-nonafluoro-butane-1-sulfonyl fluoride (60.0 L, 0.341 mmol). The mixture was stirred for 1 hour at room temperature then partitioned between water (25 mL) and ethyl acetate (25 mL). The organic was rinsed with saturated aqueous sodium chloride, dried over magnesium sulfate, filtered and evaporated. The residue was purified via chromatography using silica gel column (12 g) and ethyl acetate:hexane solvent gradient. The title compound was isolated as a pale yellow foam (0.128 g, 73%). 1H NMR (400 MHz, CDCl3, δ, ppm): 8.51 (d, J=6.6 Hz, 1H), 8.22 (d, J=7.5 Hz, 2H), 8.09 (d, J=7.8 Hz, 2H), 7.71-7.64 (m, 3H), 7.29-7.25 (m, 2H), 7.11 (s, 1H), 7.08 (t, J=7.0 Hz, 1H), 3.10 (s, 3H). MS=663 (MH)+.
