Abstract

Method for the preparation of compounds, general formula (II), ** (see formula) ** Where r = h, lower alkyl, aryl; r = h, lower alkyl, alkoxy, halogen, characterized in that a 2- (3-bis-hydroxyethylaminopropyl) -3-triazolo/4,3-a/pyridine-3 (2H) -one, of general formula (III) ** (see formula) ** It is treated beforehand with a halogenating agent, preferably thionyl chloride and successively with an excess of aniline suitably substituted, without solvent or with high boiling point solvent, preferably amyl alcohol.
