Application of 288-36-8, New Advances in Chemical Research in 2021. The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. 288-36-8, name is 1H-1,2,3-Triazole, molecular formula is C2H3N3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.

To a 100 ml round bottom flask containing 2-chloro-6-methylnicotinic acid (3 g, 17.4 mmol), copper iodide (0.16 g, 0.5 mol%), and cesium carbonate (1 1 .4 g, 35 mmol) was added a mixture of dioxane (20 ml_) and H2O (0.1 ml, 5.25 mmol). Next triazole (2.03 ml_, 35 mmol) and finally (R,R)-(-)-N,N’-dimethyl-1 ,2-cyclohexanediamine ligand (0.56 ml_, 3.5 mmol) were added. The resulting clumpy yellow slurry was stirred until evenly dispersed. Upon heating to 100 oC the reaction mixture changed from a yellow slurry to pale green. As heating progressed the slurry became less thick and was stirred more easily. The light green slurry was stirred for 4 hr at 100 oC and left to stir at room temp overnight. At this point the reaction mixture appeared as a cobalt blue slurry which was then diluted with 20 ml_ ether and 20 ml_ H2O. The resulting solution was thoroughly stirred and transferred to a seperatory funnel then the RBF was subsequently rinsed with 20 ml_ ether and H2O each. The aqueous layer was separated from the organic layer and acidified to pH 1 with 6 ml_ cone. HCI. The now brown/ lime green aqueous layer was extracted twice with EtOAc. The bright yellow organic layers were combined and dried with Na2SO4 and then cone, into a yellow powder under reduced pressure. To the yellow powder was added EtOAc to form a yellow slurry. The solids were filtered off and washed with EtOAc to give a very pale yellow powder, which was found by 1H NMR to be the Intermediate 71 (25% yield). The filtrate was cone, into a yellow solid and purified (FCC, 0-5% MeOH in DCM w/ 0.5% AcOH) to give the title product in a 20% yield. MS (ESI): mass calculated for C9H8N4O2, 204.18; m/z found 205.3 [M+H]+ 1 H NMR (400 MHz, CD3OD): 8.21 – 8.18 (m, 1 H), 7.98 (s, 2H), 7.51 (d, J = 7.9 Hz, 1 H), 2.64 (s, 3H).

The resulting mixture was stirred vigorously under a stream of nitrogen for 10 mm. The vial was placed in a pre-heated oil bath at 95 C and heated at that temperature overnight. The reaction was cooled to room temperature, diluted with EtOAc, washed with water (2X), then brine, dried over MgSO4, filtered, and concentrated. The residue was purified by column chromatography (100% EtOAc – 1%MeOH/EtOAc) to give 39.5 mg (66%) as an off-white solid. ?H NMR (500MHz, CDC13)o 8.61 (d, J1.6 Hz, 1H), 8.50 (s, 1H), 8.47 (d, J8.2 Hz, 1H), 8.10 (d, J=8.2 Hz, 1H),7.82 (s, 1H), 7.75 (s, 1H), 7.53-7.45 (m, 2H), 7.42-7.35 (m, 2H), 7.35-7.30 (m, 1H), 5.63(d,J10.7 Hz, 1H), 4.11-4.03 (m, 4H), 3.98 (s, 3H), 3.86 (dd,J=11.7, 3.0 Hz, 1H), 3.57(td,J=11.9, 1.7 Hz, 1H), 3.37 (td,J=11.9, 1.9 Hz, 1H), 3.22-3.09 (m, 1H), 2.11-2.01 (m,1H), 1.72-1.59 (m, 1H), 1.50-1.38 (m, 1H), 1.07 (d,J13.1 Hz, 1H).

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1-Methyl-1H-1,2,3-triazole, in my other articles.
