Sodium Chloride → 1-(3-Chloropropoxy)-3-nitrobenzene

Participants

Reaction Steps

Under a nitrogen atmosphere, a solution of 3-nitrophenol (15.00 g, 108.0 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 (3.42 g of an 80% dispersion in mineral oil, 114.0 mmol) in DMF (40 mL). The mixture was allowed to stir and warm to ambient temperature over 1 h. The mixture was cooled to 0-5° C., and 1-chloro-3-iodopropane (26.37 g, 127.0 mmol) was added drop-wise over 5 min. The resulting dark-brown mixture was stirred at ambient temperature for 2 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 19.75 g (85.1%) of an oil.
