In this work we describe a simple and efficient general methodology for 2-arylbenzothiazole preparation employing disulfides and carboxylic acids. The reaction is promoted by tributylphosphine that acts both in disulfide bond cleavage and as activating agent for coupling with carboxylic acids. The reaction scope was studied using bis(2-aminophenyl)disulfide and different carboxylic acids with donor/withdrawing substituents, which resulted in the desired 2-arylbenzothiazole with moderate to good yields. The method was tested with success in preparation of the amyloid probe 2-(4-aminophenyl)-6-methoxybenzothiazole that employed a substituted bis(2-aminophenyl)disulfide.
