The present invention relates compounds of formula (I): wherein R?1, R2, R3, R4 and R5¿ represent a variety of substituents; R6 represents hydrogen, CORa, CO2Ra, COCONRaRb, COCO¿2R?a, C1-6alkyl optionally substituted by a group selected from (CO2R?a, CONRaRb¿, hydroxy, CN, COR?a, NRaRb¿, C(NOH)NRaRb, CONHphenyl(C¿1-4?alkyl), COCO2R?a¿, CONHNRaRb, C(S)NR?aRb, CONRaC¿1-6alkylR?12, CONR13C¿2-6alkenyl, CONR13C2-6alkynyl, COCONR?aRb, CONRaC(NRb)NRaRb, CONRa¿heteroaryl, and phenyl optionally substituted by one, two or three substituents selected from C¿1-6?alkyl, C1-6alkoxy, halogen and trifluoromethyl); or R?6¿ represents a group of formula -CH¿2?C CCH2NR?7R8¿ where R?7 and R8¿ are as defined below; or R6 represents C¿1-6?alkyl, optionally substituted by oxo, substituted by a 5-membered or 6-membered heterocyclic ring containing 1, 2 or 3 nitrogen atoms optionally substituted by =O or =S and optionally substituted by a group of the formula ZNR?7R8¿; or a pharmaceutically acceptable salt thereof. The compounds are tachykinin antagonists and are of particular use in the treatment or prevention of depression, anxiety, pain, inflammation, migraine, emesis or postherpic neuralgia.
