Procedure

To a solution of 19.5 g. of dimethyl-5-hydroxy-2-nitroisophthalate in 150 ml. of dry ethanol are added 8.8 g. of tetramethylguanidine, followed by 29.1 g. of octadecyliodide. The mixture is refluxed for 16 hr., cooled, and poured into 700 ml. of water. The precipitate is collected and washed well with water. The dried crude product is triturated with methanol. The insoluble solid is collected, giving 32.6 g. of product, m.p. 65°-68° C., which is used without further purification.
