354793-04-7, Methyl 2,3-dioxo-1,2,3,4-tetrahydroquinoxaline-6-carboxylate is a quinoxaline compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
354793-04-7, Step B DMF (5 drops) was added to a suspension of 2,3-dioxo-1,2,3,4-tetrahydro-quinoxaline-6-carboxylic acid methyl ester (650 mg) in thionyl chloride (6.7 ML) at 23 C. The reaction mixture was then heated to reflux for 18 hrs.After cooling to 23 C. and concentration, the residue was dissolved in chloroform and washed sequentially with portions of saturated aqueous sodium bicarbonate and brine.Drying over sodium sulfate and concentration afforded 2,3-dichloro-quinoxaline-6-carboxylic acid methyl ester as a white solid. MS (M+H)+=257.1.
354793-04-7 Methyl 2,3-dioxo-1,2,3,4-tetrahydroquinoxaline-6-carboxylate 23847563, aquinoxaline compound, is more and more widely used in various fields.
