Versuchsvorschrift

9 g of phenyl 2-(4'-nitrophenoxy)benzoate, prepared as described in Example 1, are contacted with hydrogen in 50 cm3 of ethanol, in the presence of 5% palladium (100 mg) on coal. After recrystallization in 100 cm3 of a methanol-water mixture (50--50 by volume), 7.52 g of phenyl 2-(4'-aminophenoxy)benzoate (m.p. 102° C.) are obtained (yield: 92%).
