Versuchsvorschrift

Dissolved 7-fluoro-3,4-dihydrobenzo[b]oxepin-5(2H)-one (1.58 g, 8.77 mmol) in 80 mL ether and added bromine (0.497 mL, 9.65 mmol) and allowed the reaction mixture to stir at room temperature 20 hours. Reaction was complete by LCMS. Concentrated the reaction in vacuo and purified by flash chromatography (0 to 30% ethyl acetate/heptanes). Concentrated in vacuo and NMR indicated 4-bromo-7-fluoro-3,4-dihydrobenzo[b]oxepin-5(2H)-one.
