To a stirred mixture of 130 ml of water, 130 ml of ether, 7.66 g of sodium nitrate and 10.0 g of 4-ethylphenol was added 13 ml of concentrated hydrochloric acid, and the reaction was continued at room temperature for 3 days. To the reaction mixture was added 300 ml of water and the mixture was extracted with 500 ml of ether. The extract was washed with water, then a brine and dried with anhydrous sodium sulfate. The drying agent was filtered off and the solvent was distilled away under reduced pressure to give 13.0 g of 4-ethyl-2-nitrophenol.
