100 mg (0.39 mmol) of (5-Chloroimidazo[1,2-a]pyridin-8-yl)(phenyl)methanone (example L, step 3) are dissolved in 5 ml glacial acid. 30 mg (0.19 mmol) of bromine are added dropwise to the solution. The mixture is stirred for 20 h at rt. The solvent is evaporated under vacuum and the crude is purified over preparative HPLC (RP 18-Column, eluent: acetonitrile-water-gradient) to yield 64 mg (49.0% of th.) (3-Bromo-5-chloroimidazo[1,2-a]pyridin-8-yl)(phenyl)methanone.
