실험 절차

A solution of 22.9 g of chloroformic acid-3-methoxycarbonylaminophenylester in 50 ml acetic acid ester is added dropwise together with a solution of 30.5 g potassium carbonate in 150 ml water at a temperature of 10° to 15° C. into a solution of 23 g N-(2-chloroethyl)-aniline hydrochloride in 50 ml water and 50 ml acetic acid ester. During the addition the solutions are stirred. The stirring is then continued for 30 minutes at 15° C. whereupon the organic phase is separated, diluted with about 100 ml acetic acid ester and washed at 0° C. successively with dilute sodium hydroxide, water, dilute hydrochloric acid and again water. After drying on magnesium sulfate the mass is concentrated by evaporation under a reduced pressure. The residue obtained is at first oily but soon crystallizes throughout and is then recrystallized from acetic acid ester/pentane.
