Participants

Reaction Steps

5 parts of the resulting sodium salt of methyl benzimidazolecarbamate are suspended in 15 parts of dimethylformamide and 3.9 parts of triethylchlorosilane are added, in portions, at room temperature. After stirring the mixture for 12 hours under nitrogen, the solvent is distilled off under reduced pressure, tetrahydrofuran is added to the residue, and the solution is filtered. The solvent is then distilled off, giving 2.7 parts of methyl N-triethylsilyl-benzimidazole-2-carbamate; decomposition point >120° C. (active ingredient No. 1).
