Heating N-(2-methoxyphenyl)benzenecarbothioamides in refluxing nitrobenzene for 24 hours gives the corresponding benzothiazoles with intramolecular ipso substitution of the ortho-methoxy substituent. The thermal cyclization of various other N-arylthiobenzamides is also explored. Georg Thieme Verlag Stuttgart · New York.

The reactions of some N-(2,5-dimethoxyaryl) thiobenzamides were studied. It was found that nitration of 2-aryl-4,7-dimethoxybenzothiazoles produced a mixture of 5- and 6-nitrobenzothiazoles which were distinguished by synthesis of the 2-aryl-4,7-dimethoxy-6-nitrobenzothiaoles by oxidative cyclization of the corresponding nitrothiobenzanilides. The results showed that the cyclization of arylthioanilides was influenced by the nature of the ring substituents.
