Structure of (E)-4-amino-5-{[(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)imino]methyl}-1-methyl-2-phenyl-2,3-dihydro-1H-pyrazol-3-one: aerial oxidation of 4-aminoantipyrine in dimethylformamide

Structure of (E)-4-amino-5-{[(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)imino]methyl}-1-methyl-2-phenyl-2,3-dihydro-1H-pyrazol-3-one: aerial oxidation of 4-aminoantipyrine in dimethylformamide

The title compound, C22H22N6O2 (I), is the result of the aerial oxidation of the 5-methyl group of 4-aminoantipyrine to an aldehyde group followed by Schiff base formation with a second molecule of 4-aminoantipyrine. The reaction only takes place in the presence of dimethylformamide. The central uni...
