Investigations in the imidazole series

The reactions of 2-mercaptonaphth1,2-d]imidazole with 1,2-dichloro- and 1,2-dibromoethanes and the cyclization of 3-(-hydroxyethyl)- and 2-(-hydroxyethyl)mercaptonaphth1,2-d]imidazoles were studied. 2,3-Dihydro derivatives of naphth1,2-d]imidazo1,2-b]thiazole and naphth1,2-d]imidazo3,2-b]thiazole were obtained.See 1] for communication LXX.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 2, pp. 257–259, February, 1972.
