Reaction Steps

3-Benzylthio-1-phenyl-1,2,4-triazole (5 g) in dry tetrahydrofuran (50 ml) at -70° C. was treated dropwise with n-butyllithium (1.05 equivs). The solution was stirred at -70° C. for 10 minutes and cyanogen bromide (1.98 g) was added rapidly. The mixture was allowed to warm to room temperature and was then quenched with ethanol. The volatile materials were removed in vacuo, and the crude product was chromatographed on silica using dichloromethane to give 4.3 g of the desired product as a yellow oil.
