Patent ID: 8871798

Claim:
A compound of formula I or a physiologically acceptable salt of the compound of formula I, where R1 and R2 are identical or different and are independently of one another hydrogen, —(C 1 -C 6 )-alkyl, —O—(C 1 -C 6 )-alkyl, aryl, halogen or hetaryl, where alkyl, aryl and hetaryl are in each case unsubstituted or mono-, di- or trisubstituted independently of one another by F, Cl, Br, CN, —(C 1 -C 4 )-alkyl, —NH—(C 1 -C 4 )-alkyl, —N((C 1 -C 4 )-alkyl) 2 , —NH 2 , —OH, —O—CF 3 , —S—CF 3 or —CF 3 , or R3 and R4 together with the ring atoms to which they are respectively attached form a saturated or unsaturated 5-membered to 7-membered ring, where the ring consists only of carbon atoms except for the nitrogen atom which carries the group R3, or 1 or 2 of these carbon atoms are replaced by 0, S, SO, SO 2 or N—R5, where the ring is unsubstituted or mono-, di- or trisubstituted independently of one another by F, Cl, —OH, —NH—R7, —(C 1 -C 4 )-alkyl, —O—(C 1 -C 4 )-alkyl, C(O)—O—(C 1 -C 4 )-alkyl, aryl or hetaryl; X is N—R6; Y is C(O), CH 2 , CH—CH 3 or C(CH 3 ) 2 ; R5 is hydrogen, —C(O)—(C 1 -C 4 )-alkyl, —C(O)—O—(C 1 -C 4 )-alkyl, —(C 1 -C 6 )-alkyl, —(C 2 -C 4 )-alkyl-O—(C 1 -C 4 )-alkyl, —(C 2 -C 4 )-alkyl-OH, aryl or hetaryl; R7 is hydrogen, —C(O)—(C 1 -C 4 )-alkyl, —C(O)—O—(C 1 -C 4 )-alkyl, —(C 1 -C 6 )-alkyl, —(C 2 -C 4 )-alkyl-O—(C 1 -C 4 )-alkyl, —(C 2 -C 4 )-alkyl-OH, aryl or hetaryl; and R6 is hydrogen, —(C 1 -C 6 )-alkyl, —(C 3 -C 7 )-cycloalkyl, —(C 1 -C 4 )-alkylene-aryl or C(O)—O—(C 1 -C 4 )-alkyl.
