A mixture of 7.37 g. (0.030 moles) of 3-[N,N-diphenylamino]-1-chloropropane, 6.0 g. (0.024 moles) of 4-(3-methylphenyl)-piperidine hydrochloride, 3.92 g. (0.024 moles) of potassium iodide, and 5.30 g. (0.050 moles) of sodium carbonate in 60 ml. of n-butanol is refluxed for about 16 hours. Solvent is evaporated and the residue is dissolved in chloroform and washed with water. The chloroform solution is dried and passed through a column of silica gel. The product is eluted with acetonitrile. The product fractions are combined, concentrated, and converted to the maleate salt in ether. The resulting crystals recrystallized from acetonitrile to give 7.2 g. of N,N-diphenyl-4-[3-methylphenyl]-1-piperidinepropanamine butanedioate (1:1), mp. 137.5°-139.5° C.
