Versuchsvorschrift

A mixture of 10 g of 1-(p-acetamidophenyl)-2-imidazolidinone (see Example 1), 10 g of sodium hydroxide and 100 ml of water is heated under reflux for four hours. The product that crystallizes on cooling is collected and recrystallized from ethanol to yield 1-(4-aminophenyl)-2-imidazolidinone, m.p. 170°-2°.
