Abstract

Process for the obtaining of 2-formilquinoxalin-1, 4-dioxides, formula (I) cyanocyacetilhyzards, in which r is hydrogen or c - rent. Consists of the reaction of the α -cetoaldehyde of formula r ch cocho where it is the same as in the formula (I), or of its acetal with benzofuranol-oxide, in an inert solvent, in the presence of a basic catalyst, such as ammonia; following the separation of impurities by steam distillation, addition of an acid and reaction with cyanoacetilhydracine. These compounds have applications for the prevention and therapy of salmonelosis and dentures in domestic animals. (Machine-translation by Google Translate, not legally binding)
