Abstract

Procedure for the preparation of imidazo [4,5-b] pyridine of general formula: ** (See formula) ** wherein R represents a hydrogen atom or an alkyl radical containing from 1 to 4 carbon atoms and R1 represents an alkyl radical containing from 1 to 4 carbon atoms, characterized in that a diamino pyridine of general formula is reacted : ** (See formula) ** in which R is defined as above, on an isothiourea of general formula: ** (See formula) ** wherein R1 is defined as above, and then the product obtained is optionally transformed into an addition salt with an acid or a quaternary ammonium salt.
