Electric Literature of 1001401-62-2, The chemical industry reduces the impact on the environment during synthesis 1001401-62-2, name is 2-(2H-1,2,3-Triazol-2-yl)benzoic acid, I believe this compound will play a more active role in future production and life.
Intermediate 25: N-[(1S,2S)-2-Aminocvclopentvl1-2-(2H-l<2<3-triazol-2-yl)benzamide hydrochloride To a solution of tert-butyl N-[(iS,2S)-2-aminocyclopentyl]carbamate (CAS number 586961-34-4; 5 g, 24.97 mmol) in dry DMF (83 ml) was added 2-(2H-l,2,3-triazol-2- yl)benzoic acid (CAS number 1001401-62-2; 4.72 g, 24.97 mmol), HATU (14.24 g, 37.4 mmol) and triethylamine (10.44 ml, 74.9 mmol). The reaction was stirred at room temperature for 17 hours then was diluted with ethyl acetate and washed with saturated sodium bicarbonate solution and brine. The organics were dried over magnesium sulfate, filtered and concentrated in vacuo to afford a residue which was purified by column chromatography (silica, 0-100% ethyl acetate / petrol) to afford a solid. This Boc-protected intermediate was dissolved in hydrogen chloride in 1,4-dioxane (4 M, 20 ml) and stirred at room temperature for 60 hours. The solid was collected by filtration to afford the title compound.1H NMR (400 MHz DMSO-6): delta rhorhoiotaeta 1.47 - 1.83 (m, 4 H), 1.92 - 2.14 (m, 2 H), 3.32 - 3.49 (m, 1 H), 4.04 - 4.17 (m, 1 H), 7.48 - 7.59 (m, 1 H), 7.60 - 7.70 (m, 2 H), 7.77 - 7.87 (m, 1 H), 8.08 (s, 2 H), 8.33 (br. s., 3 H), 8.59 - 8.69 (m, 1 H)MS ES+: 272
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-(2H-1,2,3-Triazol-2-yl)benzoic acid, other downstream synthetic routes, hurry up and to see.
