Claim:
A compound of the formula (I) in which A is O, S, SO, NR5 or CH 2 ; R5 is H, C 1-5 -alkyl, aryl, aralkyl, acyl or alkoxycarbonyl; R4 is H or methyl; n is 1 or 2; m is 1 or 2; R1 is C 1-8 -alkylene; R2 is a group of the formula R3 is 5-membered heteroaryl which may be fused to an aryl or heteroaryl radical, where the heteroaryl and, optionally, the fused aryl or heteroaryl radical may have 1, 2 or 3 substituents selected independently of one another from C 1-5 -alkyl, C 1-5 -alkoxy, C 1-5 -alkylthio, halogen, CN, halo-C 1-5 -alkyl, halo-C 1-5 -alkoxy, hydroxy, —NH 2 , —N(R6) 2 , —NH(R6), aryl, aryloxy, aralkyl, aralkyloxy and heteroaryl, where the substituents aryl, aryloxy, aralkyl, aralkyloxy and heteroaryl may have 1, 2 or 3 substituents selected independently of one another from C 1-5 -alkyl, C 1-5 -alkoxy, C 1-5 -alkylthio, halogen, CN, halo-C 1-5 -alkyl, halo-C 1-5 -alkoxy, hydroxy, —NH 2 , —N(R6) 2 and —NH(R6); and the radicals R6 are independently of one another C 1-5 -alkyl, and physiologically tolerated salts thereof.
