Abstract
Abstract Novel 3-phenyl-tetrahydropyridines of the formula ##STR1## wherein X is selected from the group consisting of hydrogen and chlorine and R is selected from the group consisting of hydrogen, alkyl of 1 to 5 carbon atoms, alkenyl and alkynyl of 3 to 5 carbon atoms and phenyl alkyl of 1 to 3 alkyl carbon atoms with the proviso that X is not hydrogen when R is benzyl and their non-toxic, pharmaceutically acceptable acid addition salts having remarkable anorexigenic properties and inhibition of serontine collection both in vivo and in vitro and their preparation and novel intermediates.
