Synthesis of 2-amino-5(6)-(4-aminophenyl)benzimidazole derivatives: II. Reaction of 2-nitro-4-thiocyanatoaniline with 4-nitrochlorobenzene
The reaction of 2-nitro-4-thiocyanatoaniline with 4-nitrochlorobenzene in aqueous alkaline medium in the presence of phase-transfer catalyst at 95-100°C was studied with a view to obtain 4-amino-3,4′- dinitrodiphenyl sulfide. Optimal conditions for the synthesis and isolation of the product were found.
