The invention relates to compounds of the general formula (I): STR1 wherein R 1 represents a hydrogen atom or a C 1-10 alkyl, C 3-7 cycloalkyl, C 3-7 cycloalkyl-(C 1-4)-alkyl, C 3-6 alkenyl, C 3-10 alkynyl, phenyl or phenyl-(C 1-3)alkyl group;one of the groups represented by R 2, R 3 and R 4 is a hydrogen atom or a C 1-6 alkyl, C 3-7 cycloalkyl, C 2-6 alkenyl or phenyl-(C 1-3)alkyl group and each of the other two groups, which may be the same or different, represents a hydrogen atom or a C 1-6 alkyl group; and X represents a halogen atom or a hydroxy, C 1-4 alkoxy, phenyl-(C 1-3)-alkoxy or C 1-6 alkyl group or a group NR 5 R 6 or CONR 5 R 6 wherein R 5 and R 6, which may be the same or different, each represents a hydrogen atom or a C 1-4 alkyl or C 3-4 alkenyl group, or together with the nitrogen atom to which they are attached form a saturated 5 to 7 membered ring; and physiologically acceptable salts and solvates thereof.The compounds are potent and selective antagonists of ""neuronal"" 5-hydroxytryptamine receptors and are useful in the treatment of psychotic disorders (e.g. schizophrenia and mania;); anxiety, pain; gastric stasis; symptoms of gastrointestinal dysfunction such as occur with dyspepsia, peptic ulcer, reflux oesophagitis and flatulence; migraine; and nausea and vomiting.
