2-(p-Tolyl)benzoxazole was reacted with N-bromosuccinimide in the presence of benzoyl peroxide by the standard procedure to produce the known compound, 2-(4-bromomethylphenyl)benzoxazole (A). 2-(2,4-Dihydroxyphenyl)benzotriazole (B) (0.1 mole) and 2-(4-bromomethylphenyl)benzoxazole (A) (0.1 mole) was stirred in a mixture of 2-butanone (300 ml.) and potassium carbonate (100 g.). After refluxing 16 hr., the mixture was poured onto 1000 g. ice/water. Filtration, washing with water and recrystallization from methyl cellosolve/ isopropyl alcohol gave the tan, crystalline product I.
