Versuchsvorschrift
Heat 6′-methoxy-3-trifluoromethyl-[2,3′]bipyridinyl (41 g, 0.16 mol) in 30% HBr/AcOH (100 mL) to reflux for 1 hour. Cool the mixture and filter, and wash the precipitate with ether (100 mL). Transfer the precipitate into 10M sodium hydroxide (500 mL) and stir for 1 hour, and treat the solution with hydrochloric acid until the solution is pH 7. Collect the white solid by filtration and air dry to give the title compound (36 g, 93%) as a white solid.
