The invention relates to a method of preparing nitrogen macrocycles having formula (I). The inventive method comprises a step involving the reaction of compounds (II) and (III) in order to form a compound having formula (IV). Said compound is subsequently made to react with a compound having formula (V) in order to form a compound having formula (VI). The latter compound is then subjected to an acid treatment
