The Shocking Revelation of 288-36-8

I am very proud of our efforts over the past few months and hope to 1H-1,2,3-Triazole help many people in the next few years.

Electric Literature of 288-36-8, New discoveries in chemical research and development in 2021. We’ll be discussing some of the latest developments in chemical about CAS: 288-36-8, name is 1H-1,2,3-Triazole, 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.

Intermediate 46: 6-Methyl-2-[1 ,2,3]triazol-2-yl-nicotinic acid.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 C 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 C 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 Intermediate 53 (25% yield). The filtrate was cone, into a yellow solid and purified by FCC using 0-5% MeOH in DCM w/ 0.5% AcOH to give the title compound 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).Intermediate 49: 6-Methyl-2-[1 ,2,3]triazol-1 -yl-nicotinic acid.The title compound was isolated from the procedure used to prepareIntermediate 46 with a 25% yield. MS (ESI): mass calculated for ?9?8?4?2, 204.18; m/z found 205.3 [M+H]+. 1H NMR (400 MHz, CD3OD): 8.48 (d, J = 1 Hz, 1 H), 8.25 (dd, J = 7.9, 3.8 Hz, 1 H), 7.88 (d, J = 1 .1 Hz, 1 H), 7.54 (d, J = Hz, 1 H), 2.64 (s, 3H).

Step 1 : A mixture of A-24.1 (2.00 g, 1 1 .0 mmol), A-24.2 (3.80 g, 17.0 mmol), Cul (0.13 g, 0.68 mmol), A-24.3 (0.14 mL, 1 .00 mmol) and K2C03 (2.30 g, 17.0 mmol) in dry DMF (10 mL) is heated to 120°C by microwave irradiation and stirred for 40 min. The mixture is poured into water and extracted with Et20. The aq. phase is acidified with HCI (4N aq. solution) and extracted with EA. The combined organic phases are dried and concentrated to give the crude product which is purified by flash column chromatography on silica gel (using a solvent gradient from 100percent EA to EA/MeOH = 9/1 ) to provide 3.6 g of A-24.4. APCI+/-: 365 [M+H]+; HPLC (Rt): 1 .10 min (Method N).

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 22300-52-3, and we look forward to future research findings.
