Reaction Conditions

Reaction Steps

To 500 ml of dry dioxane in a reaction flask are added 9.0 g of 4-(6-hydroxyhexyloxy)-4'-nitrostilbene and 5 g triethylamine. The solution is heated to 50° C., and 3.7 g of methacryloyl chloride is added dropwise. The reaction is stirred at 45°-50° C. for about 6 hours and an additional 3.7 g of methacryloyl chloride is added. The reaction mixture is stirred for about 10 hours at 50° C., the dioxane is removed and the resultant residue is slurried with water in a blender. The solid is filtered, washed with water, and dried. The crude product is recrystallized from ethanol, mp 90°-95° C.
