Electric Literature of 1186050-58-7, The chemical industry reduces the impact on the environment during synthesis 1186050-58-7, name is 2-Fluoro-6-(2H-1,2,3-triazol-2-yl)benzoic acid, I believe this compound will play a more active role in future production and life.
General procedure: Exarm}le 69: 2-Fluoro-N-[(/5,25)-2-[(6-fluoro-l,3-benzotliiazol-2- yl)amino]cyclopentyl]-6-(2H-l,2,3-triazol-2-yl)benzamide To a solution of (iS,2S)-l-N-(6-fluoro-l,3-benzothiazol-2-yl)cyclopentane-l,2-diamine hydrochloride (Intermediate 16a, 50 mg, 0.174 mmol) in dry DCM (2 ml) was added 2- fluoro-6-(2H-l,2,3-triazol-2-yl)benzoic acid (Intermediate 21, 54.0 mg, 0.261 mmol), triethylamine (0.073 ml, 0.521 mmol) and HATU (99 mg, 0.261 mmol). The reaction was stirred at room temperature for 18 hours then diluted with DCM, washed with water, filtered through a hydrophobic frit and concentrated in vacuo. The crude product was purified by reverse phase preparative HPLC (acetonitrile / water with 0.1% ammonia) to afford the title compound.1H NMR (400 MHz, MeOD -d4) : delta ppm 1.56 – 1.72 (m, 2 H), 1.75 – 1.89 (m, 2 H), 2.16 – 2.32 (m, 2 H), 4.09 – 4.18 (m, 1 H), 4.22 – 4.31 (m, 1 H), 6.93 – 7.02 (m, 1 H), 7.19 – 7.30 (m, 2 H), 7.33 – 7.40 (m, 1 H), 7.53- 7.62 (m, 1 H), 7.74 (s, 2 H), 7.76 – 7.80 (m, 1 H) MS ES+: 441
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2-Fluoro-6-(2H-1,2,3-triazol-2-yl)benzoic acid, other downstream synthetic routes, hurry up and to see.
