Reaction Steps

1-(4-Bromobenzyl)-2-mercapto-5-hydroxymethylimidazole(1.5 g, 5 mmol) and tungstic acid(12.5 mg, 1 mol %) were suspended in 7 ml of methanol. The suspension was warmed to 40° C. and then, 30% hydrogen peroxide was slowly added dropwise. After about 2 hours, the mixture was cooled and neutralized with 1 N sodium hydroxide solution, and the precipitate was filtered. The obtained solid was washed twice with 5 ml of distilled water and 5 ml of isopropyl ether, respectively, to give 1.1 g(Yield 82%) of the title compound as a white powder.
