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.
6925-00-4, To a solution of quinoxaline-6-carboxylic acid (438 mg, 2.51 mmol) in benzene (16 mL) was added oxalyl chloride (0.26 mL, 3.02 mmol) and anhydrous DMF (0.1 mL). The reaction was stirred at room temperature for 30 minutes after which the mixture was concentrated in vacuo. The resulting yellow solid was azeotroped 3x with toluene and the product was used immediately without further purification
As the paragraph descriping shows that 6925-00-4 is playing an increasingly important role.
