Reaction Steps

To a solution of cyclopropylmethanol (0.890 mL, 11.0 mmol) in DMF (30 mL) was added sodium hydride (oil, 60%, 440 mg, 11.0 mmol), and the mixture was stirred at room temperature for 10 min. To this solution was added 2,5-dibromopyridine (2.00 g, 8.46 mmol) and the mixture was stirred at 70° C. for 1 hr. The reaction was quenched with water, and the mixture was extracted with ethyl acetate. The organic layer was washed twice with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure and the obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate=49:1 to 17:3) to give the title compound (1.88 g, yield 97%) as an oil.
