Reaction Steps

A reaction vessel is charged with 100 parts of ethyl acetate and 17.7 parts of 3'-hydroxy-2-methylacrylanilide and heated with stirring to about 65°C. Phenyl isocyanate, 12 parts, is added. No apparent reaction occurs until one part of triethylamine is added to the reaction mixture. After a slight exothermic increase in temperature, the reaction mixture is heated at reflux for one-half hour, cooled and filtered. The solids are washed with ethyl acetate and air dried to give 22.8 parts of 3'-(phenylcarbamoyloxy)-2-methylacrylanilide, m.p. 177°-178°C.
