Reaction Steps

To a mixture of 3-bromobutan-2-one (1.0 g) and 2-amino-5-iodopyridine (800 mg) was added EtOH (25 ml), and the mixture was heated at 70° C. for 30 h. The reaction mixture was cooled, diluted with water, and extracted with DCM. The DCM layer was washed with brine, dried over Na2SO4 and concentrated in vacuo. The residue was purified by silica gel column chromatography (hexane/EtOAc) to give the title compound (250 mg) as a yellow solid.
