2-Aminobenzyl cyanide was sulfonylated with 4-nitrobenzenesulfonyl chloride and reacted with 2-haloketones and N,N -diisopropylethylamine (DIPEA). 2,3-Disubstituted quinoline-4-carbonitriles have been acquired as the key merchandise originating from subsequent N -alkylation, base-catalyzed intramolecular C-arylation, aldol condensation and aromatization. A single-stage protocol was correctly analyzed for many starting up supplies. Yet, 3-substituted quinoline-4-carbonitriles were acquired as the separable by-solutions ensuing from aggressive denosylation. Some of the ready compounds showed medium action towards E. Coli .
