To a solution of sodium 4-nitrophenolate (11 grams; 56 mmole) in dimethylformamide (50 ml.) is added 4-bromo-1-butene (5 g; 37 mmole). After 2.5 hours of heating at 100° C., the reaction mixture is diluted with 400 ml. of water and extracted with light petroleum ether. The ether extracts are re-extracted with cold 5% sodium hydroxide and then washed with water and dried over magnesium sulfate. This solution is evaporated under reduced pressure and the residual oil crystallized from petroleum ether at 0° to yield 4-(4-nitrophenoxy)-1-butene.
