Abstract
12-(N, N-Dialkylaminoalkyl)quino[1,4]benzothiazines 2c-2g were obtained by alkylation of 12H-quino[1,4]benzothiazines 2a and 2b with N,N-dialkylaminoa lkyl chlorides in dioxane. 14H-Diquino[1,4]thiazine 4a was unreactive in th e same conditions. 14-(N,N-Dialkylaminoalkyl)diquino[1,4]thiazines 4b-4d we re synthesized in the annulation of 4,4'-dichloro-3,3'-diquinolinyl sulfide 3 with alkanediamines in hot phenol.
