The reaction of 2-nitro-4-thiocyanatoaniline with 4-nitrochlorobenzene in aqueous alkaline medium in the presence of phase-transfer catalyst at 95-100degreesC 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.
