Procedure
A suspension of cyclopropyl 2-anilinoacetate (2.9 g) and 2-[3-(3-methylphenyl)ureido]acetic acid in anhydrous 1,2-dichloroethane (50 cc) is heated to reflux. Thionyl chloride (1.0 cc) is then added, refluxing being maintained until the gaseous evolution has ceased. The reaction mixture is then poured into saturated aqueous sodium hydrogen carbonate solution (30 cc) and thereafter methylene chloride (50 cc) is added. The organic phase is washed with distilled water (50 cc), dried over magnesium sulphate and concentrated to dryness under reduced pressure (2.7 kPa) at 40° C. After recrystallization in acetonitrile, cyclopropylmethyl 2-{2-[3-(3-methylphenyl)ureido]-N-phenylacetamido}acetate (1.6 g), m.p. 158° C., is obtained.
