Biologically potent N-(pyridin-2-yl)benzo[d]thiazol-2-amines were conveniently synthesized from simple heteroaryl-thioureas through an oxidative C–S bond formation strategy that employed phenyliodine(III) bis(trifluoroacetate) as the oxidant. This protocol features a metal-free approach, a broad scope of substrates, short reaction times, and a simple product purification procedure.
