[GRAPHICS]Various pyridine-, quinoline-, isoquinoline-, and pyrimidine-N-oxides were converted to their corresponding alpha-imida-zoloheteroarenes in good yield by treatment with. sulfuryl diimidazole in nonpolar solvents at elevated temperatures.

Synthesis and Cytoprotective Antiulcer Activity of 2- or 4-(lH-Pyrazol-1-yl)pyrimidine Derivatives Related to Mepirizole and Dulcerozine.
(1H-Pyrazol-1-yl)-, (1H-imidazol-1-yl)-, and (1H-1, 2, 4-triazol-1-yl)phrimidines were prepared and evaluated for cytoprotective antiulcer activity. Among them, 4-methoxy-6-methyl-2-(1H-pyrazol-1-yl)pyrimidine (18) showed potent inhibition of the HCl-ethanol-induced and water-immersion stress-induced ulcers in rats, as well as low acute toxicity.
