Abstract

Procedure for obtaining new 3-guanidinoalkyl-thiophenes of general formula I **(See formula)** wherein each of the residues R1 and R2 signifies hydrogen, lower alkyl or halogen, each of the residues R3 and R4 signifies hydrogen or lower alkyl, each of the residues R5 and R6 signifies hydrogen or lower alkyl, or the residues R5 and R6 together represent lower alkylene, whereby the nitrogen atoms bonded thereto are separated by at least 2 carbon atoms, and n represents a number from 1 to 4, and from their salts, characterized in that a 3-aminoalkyl- thiophene of formula III **(See formula)** or its salts, is reacted with a compound of formula IV **(See formula)** or its salts, wherein X signifies the R6 moiety or X and Y together with the CN double bond form a CN triple bond, or Y signifies a dissociable moiety or an amino or lower alkyl-amino group, and, if desired, a compound obtained is transformed into its salts, or a salt obtained in the corresponding free compound or another salt, and/or, if desired, a mixture of obtained isomers is separated into the different isomers.
