Participants

Reaction Steps

A mixture of 7.7 g. (0.014 moles) of 3,6-dihydro-N,N-diphenyl-4-[3-(trifluoromethyl)phenoxy]-1(2H)-pyridinepropanamine ethanedioate (1:1) (preparation described in Example 16), 90 ml. of methanol, 10 ml. of acetic acid and 0.5 g. of 20% Pd/c is shaken under 50 psi. of hydrogen at room temperature for about 4 hours. The reaction mixture is then filtered, and the solvent is evaporated. The residue is initially recrystallized from aqueous isopropanol, then recrystallized from aqueous isopropanol, and again recrystallized from aqueous ethanol to give 5.0 g of N,N-diphenyl-4-[3-(trifluoromethyl)phenoxy]-1-piperidinepropanamine ethanedioate (1:1), mp 189°-190.5° C.
