SUBSTITUTED BISSBENZIMIDAZOLYL COMPOUND

Japanese Patent JPS5540689

A

(For Contracting States : BE, CH, DE, FR, GB, IT, NL) 1. Substituted bis-benzimidazolyl compounds of the general formula I see diagramm : EP0009163,P13,F1 and their physiologically compatible salts, in which A denotes 2,5-thiophenediyl, 2,5-furanediyl, p-phenylene, m-phenylene or 4,4'-phenoxyphenylene, and in which R**1 is represented by one of the general formulae IIa or IIb see diagramm : EP0009163,P14,F2 in which the radicals R**2 to R**4 independently of one another denote hydrogen, alkyl with 1-18 C atoms, cycloalkyl with 5-8 atoms, aminoalkyl, N-alkylaminoalkyl or N,N-dialkylaminoalkyl, in which an alkyl group in each case has 1-4 C atoms, morpholinoethyl, methoxyethyl, ethoxyethyl, benzyl, phenethyl or phenyl, or in which the radicals R**2 and R**3 together denote an alkylene bridge with 4, 5 or 6 CH2 groups, and in which Y denotes O, S, NH or N-R**5, in which R**5 represents alkyl with 1-4 C atoms. (For Contracting State AT) 1. Process for the manufacture of substituted bis-benzimidazolyl compounds of the general formula I see diagramm : EP0009163,P15,F1 and their physiologically compatible salts, in which A denotes 2,5-thiophenediyl, 2,5-furanediyl, p-phenylene, m-phenylene or 4,4'-phenoxyphenylene, and in which R**1 is represented by one of the general formulae IIa or IIb see diagramm : EP0009163,P15,F2 in which the radicals R**2 to R**4 independently of one another denote hydrogen, alkyl with 1-18 C atoms, cycloalkyl with 5-8 atoms, aminoalkyl, N-alkylaminoalkyl or N,N-dialkylaminoalkyl, in which an alkyl group in each case has 1-4 C atoms, morpholinoethyl, methoxyethyl, ethoxyethyl, benzyl, phenethyl or phenyl, or in which the radicals R**2 and R**3 together denote an alkylene bridge with 4, 5 or 6 CH2 groups, and in which Y denotes O, S, NH or N-R**5, in which R**5 represents alkyl with 1-4 C atoms, which comprises a) reacting a compound of the formula III R**6-A-R**6 in which A has the meanings indicated above and in which R**6 denotes see diagramm : EP0009163,P15,F3 in which Z denotes O or S and R**7 denotes alkyl or alkoxyalkyl with, in each case, 1 to 4 C atoms per alkyl radical, with a compound of the formula IV see diagramm : EP0009163,P15,F4 in which R**1 has the meanings indicated by the formula IIa or IIb, or b) reacting a compound of the general formula V see diagramm : EP0009163,P15,F5 in which A has the meanings indicated above and in which R**6 has the meanings indicated under a) under formula III, with an amine of the formula VIa or VIb see diagramm : EP0009163,P15,F6 in which R**2, R**3 and Y have the meanings indicated under formula IIa or IIb, and optionally converting a compound of the formula I, which is thus obtained, into its salt by adding a physiologically compatible acid HX, or converting a salt of the formula I, which is thus obtained, into a compound of the formula I by adding a base.
