The present invention relates to compounds of the following formula ##STR1## wherein Y is straight or branched chain alkylene containing 1-4 carbon atoms; X is hydrogen, halo such as fluoro, chloro, bromo or iodo, or lower alkyl containing 1-7 carbon atoms; Ar is phenyl, pyridyl, mono-substituted phenyl, wherein the substituent is halo such as fluoro, chloro, or bromo, or lower alkyl having 1-7 carbon atoms; and R.sub.2 and R.sub.3 are lower alkyl having 1-7 carbon atoms, or R.sub.2 and R.sub.3 together with N is an azamonocyclic ring selected from the group comprising 1-pyrrolidinyl, piperidino, 4-phenyl-4-hydroxypiperidino, 4-phenyl-4-hydroxymethylene, 4-phenyl-4-carboxypiperidino, 4-phenyl-4-carbloweralkoxypiperidino, or 4-phenyl-4-acetoxypiperidino substituted piperidino and morpholino, or an azabicycloalkanyl containing 6 to 9 carbon atoms and having at least 5 atoms in each ring of the azabicycloalkane. These compounds are useful intermediates for preparing potent antidiarrheal compounds.
