反応手順

The title compound was prepared in a manner analogous to Intermediate 1, substituting 2-iodobenzoic acid for 5-fluoro-2-iodo-benzoic acid. Two products were formed in this reaction, 2-[1,2,3]triazol-2-yl-benzoic acid and 2-[1,2,3]triazol-1-yl-benzoic acid, as a result of the tautomeric forms of 1,2,3-triazole. 1H NMR (400 MHz, CD3OD): 7.91 (s, 2H), 7.85-7.82 (m, 1H), 7.75 (dd, J=8.1, 1.0 Hz, 1H), 7.69 (td, J=7.7, 1.5 Hz, 1H), 7.60-7.55 (m, 1H).
