To a cold solution of 41.8 g of 4-nitrophenol in 250 ml of DMF was added 16.0 g of a 57% dispersion of sodium hydride in mineral oil, followed by 46.0 g of 2-diethylaminoethyl chloride. After 20 hours, the mixture was filtered, freed of solvent by evaporation under reduced pressure, the residue dissolved in ether and washed with water. Extraction with 2N hydrochloric acid and basification of the extract gave N,N-diethyl-2-(4-nitrophenoxy)ethanamine.
