Reaction Conditions

Reaction Steps

A mixture of 2,5-dibromopyridine (500 mg) and methylhydrazine (1 mL) was heated at 100° C. After cooling to room temperature, the reaction mixture was diluted with ethyl acetate and washed with a saturated brine. The organic layer was dried over sodium sulfate and concentrated in vacuo. The resultant crude product was purified by column chromatography on silica gel (solvent; chloroform) and the eluted fraction was concentrated. The residue was dissolved in tert-butanol and lyophilized to give 5-bromo-2-(N-methylhydrazino)pyridine (460 mg) as an oil.
