Procedure

1.97 g of the sodium salt of p-nitrophenol(0.01 mol), 2.16 ml of dibromoethane (0.025 mol) and 0.5 g of potassium carbonate were taken in 50 ml of dry acetone (4A activated molecular sieves) and refluxed overnight. Potassium carbonate was filtered and the solvent was removed by rotary evaporation to yield 4-(2-bromoethoxy)nitrobenzene (L) in almost quantitative yield.
