Versuchsvorschrift

4-[2-(4-Methylphenyl)ethoxy]nitrobenzene (VI) (5.14 g, 0.02 mole), sodium hydroxide powder (3.0 g) and sulfur (1.6 g, 0.05 mole) were added to a mixture of acetone (20 ml) and methanol (20 ml), followed by heating under reflux for 5 hours. After cooling, the reaction mixture was diluted with water, extracted with ether and treated in the same manner as in Example 18 to obtain 4.4 g of 4-[2-(4-methylphenyl)ethoxy]aniline (V) (yield, 96.9%).
