Procedure
A mixture of commercially available 2,5-dimethylbenzo[d]oxazole (1.000 g; 6.79 mmol), N-bromosuccinimide (1.209 g; 6.79 mmol), and commercially available dibenzoyl peroxide (11 mg; 0.046 mmol) in anh. CCl4 (10 ml) was refluxed, under nitrogen, for 17 h. After cooling to rt, the reaction mixture was filtered, and the filtrate was concentrated to dryness under reduced pressure. Purification by FC (heptane/AcOEt=9/1) afforded 5-(bromomethyl)-2-methylbenzo[d]oxazole as a yellow solid. LC-MS (conditions E): tR=0.61 min.; [M+H]+: 226.12 g/mol.
