Patent ID: 8252817

Claim:
A compound of the formula (I) in which A represents CH, R 1 represents a substituent chosen from the series consisting of (C 1 -C 6 )-alkyl, trifluoromethyl, halogen, cyano, nitro, hydroxyl, (C 1 -C 6 )-alkoxy, amino, (C 1 -C 6 )-alkoxycarbonyl, hydroxycarbonyl and —C(═O)—NH—R 4 , wherein (C 1 -C 6 )-alkyl in its turn can be substituted by hydroxyl, (C 1 -C 4 )-alkoxy, amino, mono-(C 1 -C 4 )-alkylamino, di-(C 1 -C 4 )-alkylamino or a group of the formula —NH—C(═O)—R 5 , —NH—C(═O)—NH-R 6 or —NH—SO 2 —R 7 , wherein R 5 denotes (C 1 -C 6 )-alkyl, which can be substituted by hydroxyl, (C 1 -C 4 )-alkoxy or phenyl, or phenyl, wherein phenyl, in turn, can be substituted once to three times in an identical or different manner by halogen, cyano, (C 1 -C 4 )-alkyl, hydroxyl, (C 1 -C 4 )-alkoxy, trifluoromethyl or trifluoromethoxy, R 6 denotes (C 1 -C 6 )-alkyl, which can be substituted by hydroxyl or (C 1 -C 4 )-alkoxy, and R 7 denotes (C 1 -C 6 )-alkyl, and R 4 denotes hydrogen or (C 1 -C 6 )-alkyl, which can be substituted by hydroxyl, (C 1 -C 4 )-alkoxy or phenyl, wherein phenyl in its turn can be substituted by halogen, cyano, (C 1 -C 4 )-alkyl, (C 1 -C 4 )-alkoxy, trifluoromethyl or trifluoromethoxy, R 2 represents a substituent chosen from the series consisting of halogen, cyano, nitro, (C 1 -C 6 )-alkyl, trifluoromethyl, hydroxyl, (C 1 -C 6 )-alkoxy, trifluoromethoxy, amino, hydroxycarbonyl and —C(═O)—NH—R 8 , wherein (C 1 -C 6 )-alkyl and (C 1 -C 6 )-alkoxy in their turn can be substituted by hydroxyl and R 8 denotes hydrogen or (C 1 -C 4 )-alkyl, m represents the number 0, 1 or 2, n represents the number 0, 1, 2 or 3, wherein, in the case where R 1 or R 2 occur several times, their meanings can in each case be identical or different, and R 3 represents hydrogen, (C 1 -C 6 )-alkyl or (C 3 -C 7 )-cycloalkyl, or a salt thereof.
