Exclusive formation of 2-heteroarylaminobenzothiazoles is observed when N-aryl-N'-heteroarylthioureas are treated with NBS/H2SO4.A possible explanation to account for the lack of 1,2,4-thiadiazole formation is offered, and a previous report concerning the oxidation of N-phenyl-N'-(2-pyridyl)thiourea is shown to be erroneous.
