Reaction Steps

To 8.0 g (0.045 mole) of 4-(2-chloroethyl)-1,3-dimethyl-2-oxo-imidazolidine was added 50 ml of phosphorus oxychloride, and the solution was refluxed for 18 hours, and concentrated in vacuo. The residue was dissolved in 25 ml of methylene chloride and added dropwise to 4.2 g (0.045 mole) of aniline stirring at room temperature. Stirring was continued for two hours. The solution was diluted with chloroform and washed with dilute sodium hydroxide solution. The chloroform was dried, filtered and concentrated in vacuo. The residue was dissolved in isopropyl alcohol and treated with 5.2 g (0.045 mole) fumaric acid, and the resulting fumarate was recrystallized from isopropyl alcohol and weighed 9.0 g (50% yield): m.p. 109°-112° C.
