Reaction Conditions

Reaction Steps

3 g (19.3 mmol) of 2-phenyl pyridine and 40 mg (0.716 mmol) of iron powder were mixed and stirred. It was cooled to 0° C. and 4.0 g (25 mmol) of bromine was added dropwise with stirring, and watching heat generation, and it was raised to 90° C., and stirred for 10 hours. After the reaction, this reaction mixture was dissolved in chloroform to produce a solution, which was washed with 5% sodium thiosulfate aqueous solution. The chloroform solution was dried with sodium sulfate, and then concentrated. The residue was purified by silica gel column chromatography, and the desired 2-(bromophenyl)pyridine was obtained.
