Versuchsvorschrift

p-Chlorophenol (7 g), p-nitrobromobenzene (11.0 g) and potassium carbonate (9.02 g) in dimethylsufoxide (35 ml) were heated with stirring at 120° C. for 24 hours and cooled, and the mixture was poured into water. The resulting precipitate was collected by filtration and washed with water. The resultant was heated in a mixed solvent of methanol/water [4:1,(v/v)], and allowed to cool. The resulting product was collected by filtration to give 4-(4-chlorophenoxy)nitrobenzene (12.92 g).
