Procedure
Approximately 10.9 g. of 1-(2-methoxyethyl)-4-phenyl-4-imidazolin-2-one and 1 g. of 10% palladium on carbon in 100 ml. of ethanol is hydrogenated in a Parr Shaker apparatus at 30 psig of hydrogen for 45 minutes. The catalyst is filtered, washed with ethanol, and the filtrate is concentrated to give the title compound as a waxy white solid; m.p. 82°-83° C.
