Application of 199678-06-3<\/a>,Some common heterocyclic compound, 199678-06-3, name is 4-(1-Methyl-1H-pyrazol-4-yl)benzoic acid, molecular formula is C11H10N2O2, 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.<\/p>\n

To a solution of 4-(1-methyl-1H-pyrazol-4-yl)benzoic acid (3.5 g, 17.3 mmol) in DCM (100 mL) was added N,O-dimethylhydroxylamine hydrochloride (2.0 g, 20.8 mmol),(dimethylamino)-N,N-dimethyl(3H- [1,2,3 ]triazolo[4, 5 -b]pyridin-3 -yloxy)-methaniminium hexafluorophosphate (7.9 g, 20.8 mmol) and N,N-diisopropylethylamine (8.58 mL, 51.9 mmol). The mixture was stirred at room temperature for 8 h. The reaction mixture was washed with 1 N HC1 (100 mL x 2), dried over anhydrous Na2SO4, filtered and concentrated in vacuo. The crude residue was purified by silica gel chromatography (petroleum ether \/ EtOAc = 3 : 1) to give thetitle compound (3.2 g, 75%) as a yellow solid.<\/p>\n

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 4-(1-Methyl-1H-pyrazol-4-yl)benzoic acid, its application will become more common.<\/p>\n
