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. 4928-87-4, name is 1,2,4-Triazole-3-carboxylic acid belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. Recommanded Product: 4928-87-4
To a mixture of 1H-1,2,4-triazole-3-carboxylic acid (118 mg, 1.044 mmol) and HATU (429 mg, 1.13 mmol) in DMF (2.2 mL) was added DIPEA (325 muL, 1.87 mmol) and the mixture was stirred for 15 min. Then tert-butyl 2,2-dimethylpiperazine-1- carboxylate (200 mg, 0.93 mmol) is added followed by DIPEA (240 muL, 1.38 mmol) and the mixture was stirred for another 90 min. Saturated NH4Cl was added (5 mL), followed by EtOAc (10 mL). The layers were separated and the aqueous layer extracted with EtOAc (2 x 5 mL). The combined organic extracts were washed with brine (5 mL), dried over Na2SO4, filtered and concentrated. The residue was purified by flash chromatography on silica gel eluting with 0-15% MeOH: DCM affording the title compound (263 mg, 91% yield) as an off-white solid. ESI-MS m/z calc.309.18008, found 310.35 (M+1)+ Retention time: 1.22 minutes using method C
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 1,2,4-Triazole-3-carboxylic acid, in my other articles.
