To 500 ml of toluene in a one liter round bottom flask, fitted with a condenser and magnetic stirrer, is added 14 g (0.05 M) of 4-hydroxy-4'-nitrostilbene potassium salt, 14 g of 6-iodo-1-hexanol, and 0.5 g of 18-crown-6 ether. The mixture is refluxed for about 20 hours, and then the reaction medium is filtered hot, and the product crystallizes from the toluene on cooling, m.p. 154°-157° C.
