Abstract
Two series of 2-(
N-aryl-2-oxo-2-arylethanehydrazonoyl)-6-methyl-4(3
H)-pyrimidinones
11
(
12
) were prepared by coupling of diazotized anilines with 2-(aroylmethylene)-1,2-dihydro-6-methyl-4(3
H)-pyrimidinones
2
(
3
). The spectral data of such compounds together with their 3-methyl analogs
13
(
14
) indicated that they exist predominantly in the hydrazone tautomeric form.
