Reaction Conditions

Reaction Steps

3,5-Dichloro-4-(3,5-dichlorophenoxy)benzenamine (0.1 mole) and pyridine (50 ml) are charged into a glass reaction vessel fitted with a mechanical stirrer and thermometer and are cooled to about 5° C. Ethyl chloroformate (0.125 mole) is added, with stirring, at about 5° C. Stirring is continued for a period of about 30 minutes at about 5° C., then for an additional 16 hours at room temperature. The mixture is then washed with 2 portions of water (50 ml), dried and the solventis then removed to yield the desired product ethyl [3,5-dichloro-4-(3,5-dichlorophenoxy)phenyl]carbamate.
