実験手順: 2-(4-Methylphenyl)ethyl alcohol (VIII) (2.72 g, 0.02 mole), 4-nitrochlorobenzene (IX: X=Cl) (3.15 g, 0.02 mole) and potassium hydroxide (1.4 g, 0.025 mole) were added to benzene (60 ml), and dicyclohexyl-18-crown-6 (0.2 g) was added thereto, followed by reaction at 60° C. for 10 hours. The reaction mixture was washed with water and concentrated, and the precipitated crystals were recrystallized from 95% ethanol to obtain 4.5 g of 4-[2-(4-methylphenyl)ethoxy]-nitrobenzene (VI) as white crystals (yield, 87.5%). was added followed by reaction at 60° C. for 10 hours The reaction mixture was washed with water concentrated the precipitated crystals were recrystallized from 95% ethanol to obtain

実験手順: To a solution of 65% sodium hydride (1.1 g, 0.03 mole) in dimethylsulfoxide (30 ml) were added 2-(4-methylphenyl)ethyl alcohol (VIII) (2.72 g, 0.02 mole) and 4-nitrochlorobenzene (IX: X=Cl) (3.15 g, 0.02 mole). After heating to 30° C. for 5 hours with stirring, the reaction mixture was treated in the same manner as in Example 12 to obtain 4.6 g of 4-[2-(4-methylphenyl)ethoxy]nitrobenzene (VI) as white crystals (yield, 89.5%). the reaction mixture was treated in the same manner as in Example 12 to obtain

実験手順: 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. The organic layer was separated washed with water two times concentrated in vacuo By recrystallizing the crude product from 95% ethanol
