ABSTRACT:
Thioalkyl aniline compounds, useful as chemical intermediates, for example in the preparation of anthelmintic, antibacterial and fungicidal benzimidazole compounds, are prepared by reaction of thiocyano aniline compounds with an alcohol in the presence of an alkali metal cyanide and alternatively an alkyl halide together with a dipolar aprotic solvent; an alkyl halide together with a water-immiscible solvent, a phase transfer catalyst, and the use of aqueous alkali metal cyanide; or an alkyl halide, a water-immiscible solvent and a polymer bound phase transfer catalyst.
