SYNTHESES OF 1-ARYL-1,4-DIHYDRO-6-METHYL-4-PYRIDAZONE-3-AMIDES
Abstract:
α-Methyl pyrazones have been reacted with aryl diazonium salts to form 3-arylhy-drazones-6-methyl-2,4-dioxopyranones,which are converted to 1-aryl-6-methyl-4-oxo-pyri-dazinone-3-carboxylic acids by cyclization. A series of 4-pyridazinone-3-amides were obtained by reacting the carboxylic acids with ethylchlorocarboxylate and corresponding amines. The structures of new compounds thus obtained were checked by elemental analyses,IR,NMR and MS measurements.
