A mixture of 2-(4-methylphenyl)ethyl alcohol (VIII) (13.6 g, 0.1 mole), 4-nitrochlorobenzene (IX: X=Cl) (15.8 g, 0.1 mole), toluene (92 g), tetra-n-butylammonium bromide (3.2 g, 0.01 mole) and a 50% aqueous sodium hydroxide solution (24 g) was stirred vigorously at 50° to 60° C. for 5 hours. The organic layer was separated, washed with water two times and then concentrated in vacuo. By recrystallizing the crude product from 95% ethanol, 20.6 g (yield, 80%) of 4-[2-(4-methylphenyl)ethoxy]nitrobenzene (VI) were obtained as white crystals.
