Abstract
Procedure for the preparation of 1- (monosubstituted carbamoyl) -2-benzimidazolyl-carbamates of the general formula I ** (See formula) ** (wherein R1 represents an alcohol group having 1 to 4 carbon atoms, and R2 represents an alcohol, cycloalcohyl or aralcohyl group), which comprises reacting a compound of the general formula II ** (See formula) ** (in which R1 has the same meanings as mentioned above) with a compound of the general formula III ** (See formula) ** (where R2 has the same meanings as indicated above, and A represents a phenyl group substituted by two or more electron-attracting substituents) in the presence of a base.
