6925-00-4,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.6925-00-4,Quinoxaline-6-carboxylic acid,as a common compound, the synthetic route is as follows.
To a solution of Compound 1 (3 g, 17.2 mmol) in DCM (80 mL) were added N,Odimethyihydroxylamine hydrochloride (2.0 g, 20.7 mmol), EDCI (4.0 g, 20.7 mmol), HOBt (2.3 g, 17.2 mmol) and DIEA (3.7 mL, 20.7 mmol). The resulting solution was stirred at room temperature (RT) overnight. The residue was treated with water and extracted with DCM. The organic extracts were washed with brine, dried over anhydrous Na2SO4, filtered and concentrated to give a crude oil. The crude product was purified by silica gel chromatography to afford Compound2 (2.3 g, 61.5 %).
As the paragraph descriping shows that 6925-00-4 is playing an increasingly important role.
