0.6 g of sodium hydride was added carefully to a 3 neck flask equipped with a condenser, addition funnel, and magnetic bar. 75 ml of anhydrous THF was added and the mixture stirred for 10 minutes. A solution of 4.0 g 4-(4-nitrophenylazo)aniline in 75 ml THF was added drop-wise and the flask stirred at 50° C. The temperature was raised to 95° C., and the mixture was refluxed for 6 hrs. The mixture was allowed to cool to room temperature and then 6.0 g of methacrylic acid in 20 ml THF was added drop-wise. The mixture was again refluxed for 8 hrs. The solution was cooled to room temperature. THF was evaporated to reveal a dark orange solid. The solid was washed thoroughly with dilute HCl and water. The product was recrystallized in 95% methanol. The yield was 56%.
