ABSTRACT
Reactions of 5-methylisoxazol-3-amine with diethyl ethoxymethylenemalonate derivatives are described. By this method ethyl 2-methyl-7-oxo-7H-isoxazolo[2,3-a]pyrimidine-6-carboxylate derivatives were prepared and characterized.
Keywords: Isoxazolo[2,3-a]pyrimidine-6-carboxylate, heterocyclic, aminoisoxazole
