What Kind of Chemistry Facts Are We Going to Learn About 16681-65-5

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.

Research speed reading in 2021. In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. 16681-65-5, name is 1-Methyl-1H-1,2,3-triazole belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. 16681-65-5

A solution of n-BuLi (2.5 M in hexanes, 1.5 mL, 3.75 mmol) was added dropwise by syringe to a solution of 1-methyl-1H-1,2,3-triazole (324 mg, 3.90 mmol) in dry THF (20 mL) in a dry ice-methanol bath. The suspension was stirred for 30 minutes, slowly allowing the reaction mixture to warm to -20 C. (4-Chloro-3-(4-fluorobenzyl)-2-methoxyquinolin-6-yl)(1,2-dimethyl-1H-imidazol-5-yl)methanone (0.800 g, 1.89 mmol, Intermediate 46: step b) in dry THF (10 mL) was added to the mixture via syringe and the resulting mixture was allowed to warm to ambient temperature overnight. The reaction was quenched with saturated aqueous ammonium chloride. Water was added and the aqueous mixture was extracted with dichloromethane. The combined organic layers were dried (Na2SO4), filtered, and concentrated to dryness. The crude product was purified by flash column chromatography (silica gel, 0-5% MeOH-DCM) to provide the title compound. 1H NMR (400 MHz, CDCl3) delta 8.24 (d, J=1.9 Hz, 1H), 8.05 (s, 1H), 7.71 (d, J=8.7 Hz, 1H), 7.37 (dd, J=8.7, 2.0 Hz, 1H), 7.26-7.21 (m, 2H), 7.02 (s, 1H), 6.97-6.90 (m, 2H), 5.95 (s, 1H), 4.16 (s, 2H), 4.07 (s, 3H), 3.87 (s, 3H), 3.31 (s, 3H), 2.09 (s, 3H); MS m/e 506.9 [M+H]+.
