Procedure

4-[2-(4-Methylphenyl)ethoxy]nitrobenzene (VI) (5.14 g, 0.02 mole) and sodium sulfide nonahydrate (9.6 g, 0.04 mole) were added to a mixture of 95% aqueous ethanol (50 ml) and 29% aqueous ammonia (50 ml), followed by heating under reflux for 20 hours. Sulfur deposited was filtered while hot, and the filtrate was cooled, extracted with ether and treated in the same manner as in Example 17 to obtain 4.3 g of 4-[2-(4-methylphenyl)ethoxy]aniline (V) (yield, 95%).
