Procedure

A solution of 4.75 g. of N-trifluoroacetyl-4-(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 combined filtrate and washings are evaporated. 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 a white, crystalline solid.
