実験手順
N-Bromosuccinimide (25.9 gm) was added to a cold solution of 6-methyl-2-phenylbenzoxazole (30 gm) in carbon tetrachloride (250 ml). Benzoyl peroxide (500 mg) was added and the mixture was heated under reflux for 3 hr. in the presence of u.v. light. The solid residue was filtered off. The filtrate was evaporated down slightly, treated with carbon and allowed to cool. The crystals which were formed were recrystallised from benzene to yield 6-bromomethyl-2-phenylbenzoxazole, m.p. 162° C.
