Reaction Steps

700 mg of methyl 3-chloro-2-hydrazinoquinoxaline-6-carboxylate was suspended in 3.7 mL of trimethyl orthobutyrate, followed by heating and refluxing for 2 hours. The suspension was ice-cooled, and the solid was collected by filtration and washed with cold ethyl acetate. The obtained solid was washed with hot ethyl acetate to obtain 612 mg of methyl 4-chloro-1-propyl[1,2,4]triazolo[4,3-a]quinoxaline-7-carboxylate.
