Reaction Conditions

Reaction Steps

To a solution of 2,5-dibromo-4-propylpyridine (100 mg, 0.444 mmol) in N,N-dimethylformamide (0.9 mL), dinitrile zinc (57 mg, 0.449 mmol) and tetrakistriphenylphosphine palladium (25 mg, 0.0222 mmol) were added at room temperature, and the mixture was stirred under microwave irradiation at 100° C. for 20 minutes. The reaction solution was added a saturated aqueous solution of sodium hydrogen carbonate, and extracted with hexane/ethyl acetate (4/1). The organic layer was washed with brine, dried over anhydrous sodium sulfate, and concentrated in vacuo. The obtained residue was purified by silica-gel column chromatography (hexane/ethyl acetate), and the title compound (60 mg (yield 60%)) was obtained as a colorless crystal.
