Application of 815588-93-3, New Advances in Chemical Research in 2021. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic,A common heterocyclic compound, 815588-93-3, name is 1-Methyl-1H-1,2,4-triazole-5-carboxylic acid, molecular formula is C4H5N3O2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
A mixture of ieri-butyl 6-amino-2-(2-(difluoromethyl)phenyl)-1 H-indole-1 -carboxylate (int 8) (358 mg, 1.00 mmol), 1 -methyl-1 H-1 ,2,4-triazole-5-carboxylic acid (454 mg, 2.00 mmol), HATU (570 mg, 1.50 mmol) and TEA (202 mg, 2.00 mmol) in DMF (4 m_) was stirred at rt overnight. Water (10 ml_) was added and the mixture was extracted with EtOAc (2 x 15 ml_). The combined organic layers were dried over MgS04, filtered and concentrated to dryness. The residue was purified by silica gel chromatography (gradient 30- 00 percent EtOAc in PE) to give the title compound as a yellow oil.
Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about 1-Methyl-1H-1,2,4-triazole-5-carboxylic acid.
