Participants

Reaction Steps

An ammonia gas was introduced into a solution of 2-fluoro-4-chloro-5-ethoxycarbonyloxyphenyl isocyanate (16.7 g, 64 mmol) in benzene (300 ml) while vigorously stirring on cooling in an ice bath. Precipitation of white solid was immediately observed. After thirty minutes the solid deposited was obtained by filtration and sufficiently washed with benzene and dried. This product was identified as 2-fluoro-4-chloro-5-ethoxycarbonyloxyphenyl urea (14.2 g, yield 80%).
