Procedure
4.1 parts of triethylchlorosilane and 3.0 parts of triethylamine are separately added, in portions, to 5 parts of methyl benzimidazole-2-carbamate in 50 parts of tetrahydrofuran. After 12 hours, the mixture is filtered and the solvent is distilled from the filtrate under reduced pressure. 1.6 parts of methyl N-triethylsilyl-benzimidazole-2-carbamate are obtained; decomposition point >120° C. (active ingredient No. 1).
