In a previous paper1 some physical and pharmacological properties of a series of 3-{1 -[4'-carbethoxy-4'-phenyl]piperidino} propiophenones (I: R' = C2H5) were described.The purpose of this second part is to present a series of 29 related esters (I) and to compare their pharmacological properties.These compounds are of general formula (I) in which R is a substituent such as alkyl, hydroxyl and halogen, and R' an unsubstituted alkylor aralkyl-group other than ethyl.The compounds were obtained by one of the methods of condensation mentioned in Part I,1 using the appropriate ester.The intermediate esters of 4-carboxy-4-phenylpiperidine (II) 4-Carboxy-4-phenylpiperidine and Acetophenones
