number of N-substitutedethyl 3-(n- or p-hydroxyphenyl)nipecotates were synthesized to evaluate the role of a m- or p-hydroxy substituted beta-phenethylamine moiety in narcoticantagonist action. Ethyl m- or p-methoxy-phenylcyanoacetate was alkylated with 1-bromo-3-chloropropane. The resultant chloronitriles were hydrogenated (Raney Ni) to amines and cyclized to yield the N-substitutedethyl 3-(m- or
