A number of N-substituted ethyl 34m-or phydroxypheny1) nipecotates were synthesized to evaluate the role of a m-or p-hydroxy substituted 8-phenethylamine moiety in narcotic antagonist action. Ethyl m-or p-methoxyphenylcyanoacetate was alkylated with 1-bromo-3- chloropropane. The resultant chloronitriles were hydrogenated (Raney Ni) to amines and cyclized to yield the N-substituted ethyl 3-(m-or p-methoxypheny1) nipecotates. These ...
