6-OXO-AZEPINOINDOLE COMPOUNDS AND THEIR PHYSIOLOGICALLY TOLERANTABLE ACID SALTS, PHARMACEUTICAL COMPOSITION BASED ON THEREOF AND METHODS OF THEIR SYNTHESIS

Pharmacologically active compounds corresponding to the general formula I I in which R1 represents hydrogen, a lower alkyl or cycloalkyl-alkyl group or an optionally substituted phenyl-lower alkyl group, R2 denotes hydrogen or a lower alkyl group optionally substituted in the alpha -position to the nitrogen atom by lower alkoxy, R3 denotes hydrogen, lower alkyl, lower alkoxy, halogen or hydroxyl, n represents 1 or, if the -(CH2)n- chain is in the 4-position of the ring structure, also represents 2, R4 denotes hydrogen, lower alkyl, cycloalkyl, cycloalkyl-lower alkyl or an optionally substituted phenyl-lower alkyl group, and R5 denotes hydrogen, lower alkyl, cycloalkyl, cycloalkyl-lower alkyl or an optionally substituted phenyl-lower alkyl group, or R4 and R5, together with the nitrogen atom to which they are bonded, form a heterocycle and D represents a bond, or, if R4 and R5 do not denote hydrogen, also represents the -N=CH- group, and their physiologically acceptable acid addition salts are described, and also processes and intermediates for their preparation.
