반응 단계
0.5 g of zinc octoate and 4.45 g of 3-chlorophenyl isocyanate were added to 8.2 g of phenylhydroxymalonic acid diamide in 30 ml of ethyl acetate and the mixture was kept at 50° C. for 30 minutes. After cooling, the precipitate was filtered off with suction and recrystallised from acetone. 5.6 g of phenyl-(3-chlorophenylaminocarbonyloxy)-malonic acid diamide of melting point 196°-198° C. were obtained.
