Versuchsvorschrift

To a warm mixture of 7 g. sodium 4-[15-(trifluoromethyl)pentadecylamino]benzoate in 100 ml. ethanol is added 4.7 g. ethyl α-tosyloxypropionate. After 17 hours at reflux, the cooled solution is diluted with an equal volume of water and the resultant precipitate is filtered. After washing with cold ethanol and drying, the product is crystallized from acetonitrile to yield the product as colorless crystals.
