The solution was cooled, more dimethylformamide (15 ml.) added, and the precipitated solid removed by filtration. The filtrate was evaporated in vacuo to dryness and the resultant solid stirred in chloroform, after which undissolved material was removed by filtration and the filtrate was evaporated in vacuo to dryness to give the crude product, N-[2-(3,4-dibenzyloxyphenyl)ethyl]-N-[2-(4-acetamidophenoxy) ethyl]benzylamine.
