An improved process is provided for the production of thioalkyl aniline compounds, which are known and useful as intermediates for producing anthelmintic, antibacterial and fungicidal benzimidazole compounds. According to the process a thiocyano aniline compound, an alcohol and an alkali metal cyanide are reacted, with the additional presence of an alkyl halide, and also with a dipolar aprotic solvent, or in the preence of an immiscible solvent and a phase transfer catalyst. A further improvement consists of providing said phase transfer catalyst as a polymer-bound catalyst. |
