Procedure

N-bromosuccinimide (141 mg) was added to a DMF (3 ml) solution containing 2-morpholinonicotinonitrile (100 mg), followed by stirring at 80° C. for 5 hours. The reaction solution was adjusted to room temperature. Then, aqueous saturated sodium thiosulfate solution was added, followed by extraction with ethyl acetate. The organic layer was washed with saturated saline and dried over anhydrous sodium sulfate, and then the solvent was distilled away under reduced pressure. The obtained residue was purified by silica gel chromatography (n-hexane:ethyl acetate=10:1 to 7:3), and a light yellow solid of 5-bromo-2-morpholinonicotinonitrile (120 mg) was thus obtained.
