Procedure

To a mixture of 1-(2-fluoropyridin-3-yl)propan-1-one (12.9 g) and 25% solution (70 mL) of hydrogen bromide in acetic acid was added dropwise bromine (4.4 mL), and the obtained mixture was stirred at room temperature for 3 hr. The reaction mixture was concentrated under reduced pressure to give the title compound as a red-brown oil (yield 29.6 g, quantitative).
