Abstract

Some different substituted 4-methylquinolin-2(1H)-ones have been synthesized by closing corresponding (un)substituted acetoacetanildes in the presence of ionic liquid [Bmim]OH. Obtained quinolines were conveted to its 2-chloro derivatives by reaction with POCl3. Some compounds of substituted tetrazolo[1,5-a]quinolines were synthesized by acting these 2-chloro derivatives with sodium azide in DMF as solvent. 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
