Procedure

A solution of 4.75 g. of N-trifluoroacetyl-4-(tetradecenylamino)benzoyl chloride and 1.2 g. of triethylamine in 200 ml. of warm ether is treated with 1.55 g. alanine ethyl ester and refluxed for 24 hours. The hot solution is filtered, the residue is washed with hot ether, and the solvent is evaporated from the combined filtrate and washings. After treatment of the residue with aqueous methanolic potassium carbonate, the product is precipitated by acidification, filtered, and dried. Crystallization from acetone yields the product as a white, crystalline solid.
