実験手順
Dissolve 1-(3-trifluoromethyl-pyridin-2-yl)-ethanone (2.10 g, 11.1 mmol) in HBr (30% by wt in AcOH) (14 mL). Cool the mixture to 0° C. and add bromine (0.62 mL) drop wise. Allow the resulting solution to warm to room temperature and stir for 3 hours. Concentrate the reaction under reduced pressure to yield the title compound as its HBr salt.
