To a 500 mL three-necked, round-bottomed flask equipped with a magnetic stirrer, dropping funnel, condenser, thermometer, and a nitrogen atmosphere are charged 5.00 g (14.7 mmol) of 2-(2,4-dihydroxyphenyl)-4,6-bis-phenyl-s-triazine and 300 mg of aluminum isopropoxide. The mixture is heated to 160° C. and 17.3 g of α-methylstyrene are added all at once. After stirring at this temperature for 26 hours the mixture is allowed to cool and a portion of heptane is added. Vacuum filtration affords 4.45 g of the title compound as a yellow solid.
