Reaction Steps

To a solution of 5-cyclopropylpyridin-2-amine (1.33 g) in acetic acid (15 mL) was added bromine (762 μL) at 0° C., and the mixture was stirred at room temperature for 2 hr. The reaction mixture was basified with 1N aqueous sodium hydroxide solution at 0° C., and extracted with ethyl acetate. The extract was dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (NH, ethyl acetate/hexane) to give the title compound (1.11 g).
