For laboratory use it seemed very desirable to develop a simple method of preparing 2- mercaptobenzothiazole which could be extended to several new derivatives. The present paper outlines a method of preparing 2-mercaptobenzothiazole in one step from o- nitrochlorobenzol, a comparatively cheap material. The method is capable of extension to the preparation of other derivatives such as the halogen, amido and carboxyl derivatives ...
