Synthesis of hetarylquinolines proceeding from 2-[(2-methylquinolin-4-yl)sulfanyl]acetohydrazide substituted in the benzene ring

Abstract

At intramolecular cyclization of phenylhydrazinocarbothioamide in alkaline and acidic media quinolyl-substituted triazoles and thiadiazoles are obtained. Quinolyl-substituted thiazolidines and thiazolidinones were obtained at interaction of phenylhydrazinocarbothioamides with bromoacetophenone and ethyl bromoacetate.
