실험 절차
Aqueous 2 N sodium hydroxide solution was added dropwise to a stirred suspension of 2 g of imidazo-[1,2-a]-quinoxaline-2-carboxylic acid in 20 ml of water until dissolution occured at a pH of 9-10. Acetone was added to the mixture to cause precipitation and the mixture was filtered to obtain 1.8 g of sodium imidazo-[1,2-a]-quinoxaline-2-carboxylate melting at >300° C.
