Reactions of 2-aminobenzothiazoles with phenyl glycidyl ether

In acidic media 2-aminobenzothiazole and its derivatives react with phenyl glycidyl ether at the ring nitrogen atom, while in alkaline media they react at the exocyclic nitrogen atom. The structures of the compounds were proved by spectral methods and alternative synthesis.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 5, pp. 685–691, May, 1991.
