Reaction Steps

To 2,5-dibromopyridine (500 mg, 2.1 mmol) and 3-cyano-1-propanol (270 mg, 3.1 mmol) in DMSO (2 mL) was added IM sodium hexamethyldisilazide (2.1 mL, 2.1 mmol). The reaction was stirred at room temperature overnight. EtOAc was added to the reaction and the mixture was washed with water (2×10 mL). The EtOAc fraction was dried over anhydrous sodium sulfate and evaporated on a rotary evaporator. The crude product was purified by flash column chromatography over silica gel using 40%EtOAc/hexanes to give 200 mg of 5-bromo-2-cyanopropyloxypyridine as a pale yellow solid (39.3%).
