Abstract
Process for the obtaining of 2 (1H) pyridinones and their salts of addition of acid or cationic salts, of formulas (I), in which r is hydrogen, alkyl or lower hydroxyalyllide; r is lower rent; and q and py can be various types of radicals. It consists in the reaction of a compound of formula (II), in which r and py have the same meaning as in formula (I), with N-r -alfa-cyanoacetamide. The reaction is carried out in an inert solution at the reflux temperature of the mixture. From the product obtained their derivatives can be obtained, following conventional methods. These compounds have pharmacological applications as cardiotonic agents. (Machine-translation by Google Translate, not legally binding)
