Procedure

N-[4-(3,5-Dicyanophenoxy)-3,5-dicyanophenyl]-N'-(2,2-dimethoxyethyl)-N'-methylurea (0.02 mole), water (30 ml) and concentrated hydrochloric acid (3 ml) are charged into a glass reaction vessel fitted with a mechanical stirrer, thermometer and condenser. The mixture is refluxed for a period of about 30 minutes then cooled and extracted with ethyl acetate. The extract is washed with dilute aqueous sodium bicarbonate, with two portion of water and is then dried. The ethyl acetate is removed by mild warming under reduced pressure to yield the desired product 1-methyl-3-[4-(3,5-dicyanophenoxy)3,5-dicyanophenyl]-4-imidazolin-2-one.
