The aldol condensation product (4) of 4-acetylpyridine (2) and diethyl mesoxalate (3) was converted to pyridazinecarboxylic acid hydrazide (6). Curtius reaction of 6 gave aminopyridazinone (7). The condensation of (4-pyridinyl)glyoxal (17) with aminomalonamide (9) yielded pyrazinecarboxamide (18) which was transformed to aminopyrazinone (19) by the Hofmann reaction. Curtius reaction of l,2,4-triazinone-5-carboxylic acid (21b) gave aminotriazinone (22). Demethylation of methoxypyrimidine (29) prepared from methyl 2-methoxyformylacetate (25) and isonicotinamidine (26) gave pyrimidinol (30).
