These common heterocyclic compound, 1001401-62-2, name is 2-(2H-1,2,3-Triazol-2-yl)benzoic acid, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. SDS of cas: 1001401-62-2
j0814] To the title compound of step B (140 mg, 0.5 mmol) and intermediate A-i (113 g, 0.6 mmol) in DMF (4 mE) was added DIPEA (230 jt, 1.4 mmol) and HATU (155 g, 0.6 mmol). Upon completion of the reaction, purification was performed using Agilent prep method X to give the title compound (172 g, 74%). MS (ESI) mass calcd. for C2QH,8F3N70, 429.2; mlz found 430 [M+H]. 1H NMR (CDC13): 8.32 (s, 0.3H), 8.17 (s, 0.7H), 7.99-7.89 (m, i.5H), 7.88-7.77 (m, 1 .5H), 7.62-7.30 (m, 4H), 6.24-6.15 (m, 0.3H),4.86 (s, 0.7H), 4.76 (d, J=5.4 Hz, 0.3H), 4.45-4.23 (m, 1H),
The synthetic route of 2-(2H-1,2,3-Triazol-2-yl)benzoic acid has been constantly updated, and we look forward to future research findings.
