Abstract
Abstract Compounds of formula (I), or a pharmaceutically acceptable salt thereof, or a pharmaceutically acceptable solvate of either of the foregoing: wherein one of X and Y is CO and the other is NH; p and q each independently are 0 to 2; R 1 , R 2 and R 3 are each independently hydrogen, C 1-6 alkyl, hydroxy, C 1-6 alkoxy, C 1-6 alkylthio or halo; or any two on adjacent carbon atoms together are C 1-2 alkylenedioxy and the third is hydrogen, C 1-6 alkyl, C 1-6 alkoxy or halo; and R 4 is C 1-7 alkyl, C 3-8 cycloalkyl, C 3-8 cycloalkyl-C 1-2 alkyl, or a group (CH 2 ) t R 5 where t is 1 or 2 and R s is thienyl or furyl optionally substituted by one or two substituents selected from C 1-6 alkyl, C 1-6 alkoxy, trifluoromethyl or halogen, or is phenyl optionally substituted by one or two substituents selected from C 1-4 alkoxy, trifluoromethyl, halogen, nitro, carboxy, esterified carboxy, and C 1-4 alkyl optionally substituted by hydroxy, C 1-4 alkoxy, carboxy, esterified carboxy or in vivo hydrolysable acyloxy, having 5-HT antagonist activity, a process for their preparation and their use as pharmaceuticals.
