Abstract:

Reaction of different substituted 2-chloro-4-methylquinolines with sodium azide changed the direction to substituted tetrazolo[1,5-a]quinolines instead corresponding 2-azido-4-methylquinolines. Required 2-chloro-derivatives were obtained from substituted 4-methylquinolin-2(1H)-ones, which were synthesized by ring closing corresponding (un)substituted acetoacetanildes in the presence of ionic liquid [Bmim]OH. The structures of obtained compounds have been confirmed by using spectroscopic methods (IR, NMR and MS).

Keywords: Knorr synthesis, 4-methylquinolin-2(1H)-ones, ionic liquid, sodium azido.
