To a solution of 6.8 g of sodium ethoxide and 15 g of m-nitrophenol in 250 ml of dimethylformamide, 28 g of cyclohexyloxyethyl p-toluenesulfonate were added. After heating at 100° C. for 2 hours, the resulting mixture was diluted with water and extracted with benzene. The solvent was removed under reduced pressure, and the residue was purified by vacuum distillation to give 23.8 g of 3-[2-(cyclohexyloxy)ethoxy]nitrobenzene. B.P., 118°-124° C./0.1 mmHg. nD27 1.5380.
