Patent ID: 7851630

Claim:
A compound of formula (1) or a pharmaceutically acceptable salt, or a stereoisomer of any of the foregoing wherein: R1 is chosen from H, alkyl(1-6C), alkyl(1-3C)cycloalkyl(3-6C), carbalkoxy(2-7C) and acyl(2-7C); [ ] m symbolizes —(CH 2 ) m — wherein m is chosen from 0 and 1; R 2 is chosen from halogen, CF 3 , alkyl(1-6C), alkyl(1-3C)cycloalkyl(3-6C), phenyl, amino, aminoalkyl(1-3C), alkyl(1-3C)amino, dialkyl(1-3C)-amino, cyano, cyanoalkyl(1-3C), hydroxy, hydroxyalkyl(1-3C), (1-3C)alkoxy, OCF 3 , acyl(2-7C), trifluoroacetyl, aminocarboxyl, (1-3C)alkylsulphonyl and trifluoromethylsulphonyl, and n is an integer ranging from 0 to 4, with the proviso that when n is 2, 3 or 4, the R 2 substituents may be either the same or different; A is chosen from saturated and partially unsaturated rings; [ ] o and [ ] p symbolize —(CH2) o — and —(CH 2 ) p — respectively, with the proviso that —CH— is possible when A is a partially unsaturated ring, and o and p independently are chosen from 0, 1 and 2; R 3 , R 4 , R 5 and R 6 , which are different or identical, are chosen from hydrogen, alkyl(1-3C), alkyl(1-3C)-cycloalkyl(3-6C), CH 2 OH and (R 3 and R 5 ) or (R 3 and R 6 ) or (R 4 and R 5 ) or (R 4 and R 6 ) together can form an alkylene bridge of 1 to 3 carbon atoms, with the proviso that when o is 2, R 3 is hydrogen, and when p is 2, R 5 is hydrogen; and [ ] q symbolizes —(CH 2 ) q — wherein q is an integer ranging form 0 to 2.
