실험 절차

A suspension of 8-(3-(trifluoromethyl)phenyl)-[1,2,4]-triazolo[1,5-a]pyridin-2-amine (1.0 g, 3.6 mmol, 1 equiv), methyl 4-iodobenzoate (0.95 g, 3.6 mmol, 1.0 equiv), palladium (II) acetate (0.080 g, 0.36 mmol, 0.10 equiv), cesium carbonate (2.34 g, 7.18 mmol, 2.0 equiv), and Xantphos (0.10 g, 0.17 mmol, 0.047 equiv) in 1,4-dioxane (20 mL) was heated to 80° C. After 16 h, the reaction mixture was concentrated in vacuo, and the resulting residue was diluted with methanol and water. The solid was collected by filtration and rinsed sequentially with water, isopropanol, and hexanes to afford crude methyl 4-(8-(3-(trifluoromethyl)phenyl)[1,2,4]triazolo[1,5-a]pyridin-2-ylamino)benzoate (1.07 g, 72%). LCMS (ESI) m/z: 413.0; 1H NMR (400 MHz, DMSO-d6) δ: 10.29 (s, 1 H), 8.88 (m, 1 H), 8.63 (s, 1 H), 8.40 (m, 1 H), 8.02 (m, 1 H), 7.78-7.90 (m, 6 H), 7.20 (m, 1 H), 3.80 (s, 3 H).
