Abstract
Process for the preparation of new heterocyclic amines of the general formula ** (See formula) ** in which Ar means a phenyl radical, optionally substituted by inert substituents, such as halogen atoms, lower alkyl groups or lower alkoxy groups, and R means hydrogen or a hydrocarbon radical, optionally interrupted by oxygen and/or sulfur and optionally substituted in double bonds by halogen, characterized in that an optionally substituted thiobenzamide of the general formula is reacted ** (See formula) ** with cyanacetic acid or substituted cyanacetic acid of the general formula ** (See formula) ** in the presence of a condensing agent, in particular of phosphoric oxychloride or phosphoric trichloride.
