Abstract
Compounds of formula: ##STR1## in which: either R.sub.1 represents 4-phenyl-1,2,3,6-tetrahydro-1-pyridyl or 4-(4-fluorophenyl)-1,2,3,6-tetrahydro-1-pyridyl, R.sub.2 represents hydrogen, alkoxy of 1 or 2 carbon atoms, hydroxyl, alkyl, alkylthio, alkylcarbonyloxy, phenylalkylcarbonyloxy, phenylalkyl or --NR.sub.4 R.sub.5 in which R.sub.4 represents hydrogen or alkyl and R.sub.5 represents alkyl, phenyl, monohalogenated phenyl or pyridyl, and R.sub.3 represents a hydrogen atom, or else R.sub.2 represent phenyl and R.sub.3 represents hydrogen or hydroxyl; PA1 or R.sub.1 represnets 4-phenyl-1-piperazinyl whose phenyl nucleus has a substituent halogen atom or hydroxyl radical in the 4-position, R.sub.2 represents alkoxy and R.sub.3 represents hydrogen; it being understood that when R.sub.1 represents the 4-phenyl-1,2,3,6-tetrahydro-1-pyridyl radical, R.sub.2 is not hydroxyl and that, unless otherwise stated, the alkyl and alkoxy radicals and the alkyl and alkoxy portions contain 1 to 4 carbon atoms each in a straight or branched chain, and addition salts thereof with an inorganic or organic acid, are useful in therapy for their serotonin antagonist properties.
