Investigation of the products of the reaction of epichlorohydrin with aromatic amines

5,6-Dichlorobenzof]quinoline is formed by the action of thionyl chloride on 3-hydroxy-5-chloro-1,2,3,4-tetrahydrobenzof]quinoline hydrochloride. 7-Chlorobenzof]quinoline and 7-chloro-1,2,3,4-tetrahydrobenzof]quinoline are obtained in good yields by heating 3-hydroxy-7-chloro-1,2,3,4-tetrahydrobenzof]quinoline with orthophosphoric acid, while benzof]quinoline is also obtained by heating it with polyphosphoric acid.See 1] for communication VII.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 1, pp. 108–111, January, 1971.
