Abstract
A procedure for the preparation of new benzimidazolyl -2-aminoimidazolines of formula (I): **(See formula)** and salts and solvates thereof, where R is hydrogen or lower acyl; R1 and R2 are each hydrogen or lower alkyl; R3 is hydrogen or a lower hydrocarbon; R4, R5, R6 and R7, which may be the same or different, are each selected from halogen, hydrogen, nitro, nitrile, lower aliphatic hydrocarbon, halogenated lower aliphatic hydrocarbon, sulfonic acid, lower esterified carboxyl, carboxylic acid, hydroxyl, hydroxyl. lower acylated, amino, dialkyl (lower) amino, lower acylated amino, amino (lower) oxycarbonylated amino or a lower hydrocarbon hydroxyl group, the process of which comprises the reaction of a compound of formula (III): **(See formula)** where R11 is a nitrile group or an amidino group, with a diamine of formula (IV): NH2 - CHR2- CHR3-NH2 (IV) and then, if desired, variation of the groups R4, R5, R6 and R7 in a known manner or acylation of a nitrogen atom of the imidazoline ring.
