Compounds of formula (I):
and pharmaceutically acceptable salts and N-oxides thereof, wherein:
a and b are separately 0, 1 or 2;
X is -CO-NR- wherein R is hydrogen or C1-4 alkyl, or -NH-CO-;
R1 is a C1-6 alkoxy group;
R2 and R3 are the same or different and are hydrogen, halogen, CF3, C1-7 acyl, C1-7 acylamino, C1-6 alkyl-S(O)n wherein n is 0, 1 or 2, nitro or amino, C1-6 alkoxy, aminocarbonyl or aminosulphonyl optionally substituted by one or two C1-6 alkyl groups;
or R1 and R2 taken together an adjacent carbon atoms are methylenedioxy or ethylenedioxy in which case R3 is any one of the groups given for R2 and R3 above;
and either
R4 is hydrogen, C1-6 alkyl or phenyl; and R5 is hydrogen; in which case when a and b are 1 and R4 and R5 are both hydrogen then the dotted line may represent a double bond between the two adjacent carbon atoms (in the R4/R5 substituted ring) opposing the two adjacent nitrogen atoms;
or
R4 and R5 are attached to two adjacent carbon atoms and form together with these two carbon atoms a fused benzene ring, which benzene ring may be substituted by C1-6 alkyl, C1-6 alkoxy, CF3 or halogen;
there being a minimum of two carbon atoms between the amide nitrogen and each of the ring nitrogens having useful pharmacological activity, a process for their preparation and their use.
