Procedure

A flask containing 10.0 g. 4-[15-(trifluoromethyl)pentadecylamino]benzoic acid, 3.3 g. lactic acid, 500 mg. toluenesulfonic acid and 500 ml. toluene is equipped with a Soxhlet extractor charged with activated 4 A Linde molecular sieves. The solution is refluxed for 24 hours, during which time the Soxhlet extractor is charged twice more with fresh sieves. The hot solution is filtered and allowed to cool, whereupon the product separates as off-white crystals.
