実験手順

To 2-methyl-4-(1-(4-(trifluoromethoxy)phenyl)-1H-1,2,4-triazol-3-yl)benzoic acid (0.412 g, 1.134 mmol) in a 100 mL round-bottomed flask equipped with a stir bar under N2 was added isopropyl alcohol (11 mL), triethylamine (0.205 ml, 1.474 mmol) and diphenyl phosphorazidate (0.319 ml, 1.474 mmol). The reaction was stirred at room temperature overnight. The resultant solid was filtered, washed with isopropyl alcohol followed by hexanes and dried under vacuum providing the title compound as a white solid (0.294 g, 0.757 mmol, 67%): 1H NMR (300 MHz, CDCl3) δ 8.60 (s, 1H), 8.13 (s, 1H), 8.11-8.02 (m, 2H), 7.84-7.77 (m, 2H), 7.40 (d, J=8.6 Hz, 2H), 2.74 (s, 3H); 19F NMR (376 MHz, CDCl3) δ −58.02; ESIMS m/z 389 ([M+H]+).
