Reaction Steps
Under a nitrogen atmosphere, a solution of 5-chloro-3-pyridinol (15.00 g, 115.8 mmol) in N,N-dimethylformamide (DMF) (10 mL) was added drop-wise over 5 min to a cold (0-5° C.), stirring slurry of sodium hydride (3.69 g of an 80% dispersion in mineral oil, 123.0 mmol) in DMF (15 mL). The mixture was allowed to stir and warm to ambient temperature over 1 h. Next, 1-chloro-3-iodopropane (28.4 g, 138.9 mmol) was added drop-wise over 5 min. The resulting dark-brown mixture was stirred at ambient temperature for 4 h. Water (25 mL) was added, followed by saturated NaCl solution (25 mL), and the mixture was extracted with ether (4×50 mL). The combined ether extracts were dried (Na2SO4), filtered, and concentrated by rotary evaporation to a residue that was dried briefly under high vacuum to give 17.22 g (73.0%) of an oil.
