실험 절차

The 4-fluorophenylacetic acid (20 g, 0.13 mol), benzoyl peroxide (130 mg, 0.540 mmol), and N-bromosuccinimide (23.1 g, 0.130 mol) were combined in 500 ml carbon tetrachloride under N2 and refluxed under UV irradiation (GE sunlamp) for 5 hours. The reaction was cooled to RT and the succinimide filtered away. The carbon tetrachloride was removed in vacuo and the remaining oil recrystallized from hexanes yielding 26.2 g (87%) of product as a light yellow solid. EA, MS(FD).
