Reaction Steps

5.0 g. of sodium borohydride, (0.131 moles) is added portionwise to a solution of 13 g. (0.032 moles) of 4-(3-methylphenoxy)-1-[3-(N,N-diphenylamino)propyl]pyridinium iodide in 200 ml. of methanol over a 10 minute period, allowing the temperature to reach reflux. The reaction is refluxed another 20 minutes. Solvent is evaporated. The residue is dissolved in chloroform, washed with sodium carbonate solution, and dried. Solvent is evaporated. The residue is converted to the maleate in ether and recrystallized from acetonitrile to give 10.9 g. of 3,5-dihydro-4-(3-methylphenoxy)-N,N-diphenyl-1(2H)-pyridinepropanamine butenedioate (1:1), mp. 164°-166° C.
