After cooling, the reaction mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with water, dried over anhydrous sodium sulfate, concentrated under reduced pressure and chromatographed on silica gel to give 1-(3-morpholinopropoxy)-1,4-diphenylbutane. M.P., 138°-139° C. (oxalate).
