Procedure

The carbamate used as the starting material is obtained by reacting an isocyanate with an alcohol or a carbamic acid chloride with an alcohol in the presence of an alkali, in the conventional manner. For example, reaction of 3,5-dichlorophenyl isocyanate with methyl alcohol gives methyl N-(3,5-dichlorophenyl)-carbamate (melting point 121° C.).
