실험 절차

Prepared according to the procedure for 2-(2H-1,2,3-triazol-2-yl)-5-(trifluoromethyl)benzoic acid (Intermediate 37a) and 2-(1H-1,2,3-triazol-1-yl)-5-(trifluoromethyl)benzoic acid (Intermediate 37b) from 2H-1,2,3-triazole (CAS number 288-36-8; 1.0 g, 10.86 mmol) and 5-chloro-2-iodobenzoic acid (CAS number 13421-00-6; 2.00 g, 7.24 mmol). The crude solid was purified by column chromatography (silica, 0-3% methanol/DCM) to afford 5-chloro-2-(2H-1,2,3-triazol-2-yl)benzoic acid (Intermediate 38a; also commercially available CAS number 1293284-54-4). The mixed fractions were further purified by column chromatography (silica, 0-3% methanol/DCM) to afford 5-chloro-2-(1H-1,2,3-triazol-1-yl)benzoic acid (Intermediate 38b).
