Process for producing 5- (1-phenyl-1H-pyrazol-4-yl) -nicotinamide derivatives and analogous compounds without isolating or purifying the phenylhydrazine intermediate

摘要

By converting aniline to a 1-phenyl-1H-pyrazole derivative without isolating or purifying the phenylhydrazine intermediate, 5- (1-phenyl-1H-pyrazol-4-yl represented by the formula (I) is obtained. ) -Methods for producing nicotinamide derivatives and analogous compounds. Embedded image
