A series of novel N-alkyl or oxyalkyl arylpiperidine derivatives have been prepared, including their pharmaceutically acceptable acid addition salts, wherein the N-alkyl or oxyalkyl side chain is further substituted by certain aryl or heterocyclic ring groups. These particular compounds are useful in therapy as neuroleptic agents for the control of various psychotic disorders. Typical and preferred member compounds include 4-4-4-(2-methoxyphenyl)-1-piperidinyl]ethyl}phenyl}}thiazole-2-amine, 4-4-4-[4-(2-methoxyphenyl)-1-piperidinyl]-n-butyl}phenyl}}thiazole-2-amine, 3-4-[4-(2-methoxyphenyl)-1-piperidinyl]-n-butyl}-1,8,8-trimethyl-3-azabicyclo[3.2.1]heptane-2,4-dione, 5-2-[4-(2-methoxyphenyl)-1-piperidinyl]ethyl}oxindole and 3-2-[4-(1-naphthyl)-1-piperidinyl]ethyl}2-methyl-4H-pyrido[1,2-a]pyrimidine-4-one, respectively. Methods for preparing all these compounds from known starting materials are provided.
