Butanamide derivative (1) coupls smoothly with arenediazonium salts to afford the hydrazone (3). The latter product reacts with dimethylformamide – dimethylacetal (DMF-DMA) and or malononitrile to afford the substituted 1,4dihydropyridazines (5,6). Several new pyran (8), thiophene (9), pyrazole (14) and isothiocyanate derivatives (17,18) have been synthesized by the reactions of butanamide with...
متن کاملSynthesis of pyrazolone derivatives and their biological activities
3-Methyl-1-phenylpyrazol-5-one and its derivatives prepared using ethyl acetoacetate, phenyl hydrazine and its derivatives. Ethyl acetoacetate reacted with phenylhydrazine at reflux temperature to give 3-methyl-1-phenylpyrazol-5-one crude and recrystlized from diluted ethanol to give pure 3-methyl1-phenylpyrazol-5-one. Different pyrazolone derivatives were prepared by using different phenyl hyd...
متن کاملSynthesis of chloro pyrazolone derivatives and their biological activities
3-Methyl-5-chloro-1-phenylpyrazol and its derivatives were prepared by the reaction with 3methyl -1-phenylpyrazol-5-one, phosphorous oxytrichloride and N-N dimethyl aniline respectively using catalyst. These compounds were further treated with alcohols and sodium hydroxide to form ether linkage. Ethyl acetoacetate reacted with phenylhydrazine at reflux temprature to give 3-methyl-1phenylpyrazol...
