The present invention relates to compounds of the formula (I):
wherein
R1 is hydrogen, halogen, C1-6alkyl, C1-6alkoxy, CF3, NO2, CN, SRa, SORa, SO2Ra,CO2Ra, CONRaRb, C2-6alkenyl, C2-6alkynyl or C1-4alkyl substituted by C1-4alkoxy, where Ra and Rb are hydrogen or C1-4alkyl;
R2 is hydrogen, halogen, C1-6alkyl, C1-6alkoxy substituted by C1-4alkoxy or CF3;
R3 is hydrogen, halogen or CF3;
R4 is selected from the definitions of R1;
R5 is selected from the definitions of R2;
R6 is a 5-membered or 6-membered heterocyclic ring containing 2 or 3 nitrogen atoms optionally substituted by =O, =S or a C1-4alkyl group, and optionally substituted by an aminoalkyl group;
R9a and R9b are hydrogen or C1-4alkyl, or R9a and R9b are joined to form a C5-7 ring;
X is C1-4alkylene optionally substituted by oxo; and
Y is a C1-4alkyl group optionally substituted by hydroxyl;
with the proviso that if Y is C1-4alkyl, R6 is substituted at least by an aminoalkyl group;
and pharmaceutically acceptable salts and prodrugs thereof.
The compounds are of particular use in the treatment of pain, inflammation, migraine and emesis.
