METHOD FOR PREPARING 4-(3-PYRIDINYL)-1H-IMIDAZOLE AND THE INTERMEDIATES USED

摘要

The invention concerns a method for preparing compounds of formula (I) wherein R represents a hydrogen atom or an alkyl radical containing up to 8 carbon atoms, characterised in that it consists in subjecting a compound of formula (II) wherein alc represents the residue of an alkyl radical containing up to 4 carbon atoms to the action of a compound of formula (III): RCONH2, wherein R retains its previous meaning, to obtain the compound of formula (IV) wherein R retains its previous meaning which is subjected to cyclization to obtain the desired product of formula (I).
