Abstract

Condensation of 2-hydrazino-4-methylquinoline (1) and acetylacetone gives a compoundA, which has the structure of 3,5-dimethyl-1-(4-methylquinolino)-pyrazole (2) and not of 4-methylquinolino-(2,3—c)-3,5-dimethyl-1H-1,2-diazepine (3) assigned earlier. The structure2 was confirmed on the basis of1H-NMR,13C-NMR, IR spectral data and its unambiguous synthesis.
