Versuchsvorschrift
A mixture of 3.98 g of methyl 4,5-diamino-2-methyl benzoate and 40 mL of diethyl oxalate was stirred at 145° C. for 3 hours. After cooling to room temperature, the solid was collected by filtration, washed with diethyl ether, and dried under reduced pressure to obtain 4.75 g of methyl 7-methyl-2,3-dioxo-1,2,3,4-tetrahydroquinoxaline-6-carboxylate.
