5,6-Dihydro-4h-imidazole[4,5,1-i,j]quinoline derivatives

2-Alkyl(dialkyl)amino derivatives of I and their respective cyclic ammonium salts were obtained by reaction of the 2-chloro derivative of 5,6-dihydro-4H-imidazole [4,5,1-i,j ]quinoline (I) and its methiodide with amines. The eycloammonium salt was converted into 2-amino(alkylimino)-l,2-dihydro derivatives of 5. Methoxy- and methyl-substituted I readily formed 2-amino derivatives by reaction with sodium amide. Comparison of the UV spectra of the 2-amino derivative of I and its fixed tautomeric form indicates that the 2-amino derivative of I exists primarily in the amino form in dioxane and CC14.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 10, pp. 1410–1413, October, 1970.
