Reaction Steps

4-(1-Methyl-1,2,3,4-tetrazol-5-yl)thiobutyl 1-methyl-1,2,3,4-tetrazol-5-yl sulfone (1 g) is dissolved in formic acid (10 ml), and thereto is added with stirring 30% hydrogen peroxide (0.4 g) at room temperature, and the mixture is stirred for 3 hours. Water is added to the mixture and the precipitated crystals are collected by filtration and recrystallized from ethanol-chloroform to give 4-(1-methyl-1,2,3,4-tetrazol-5-yl)sulfinylbutyl 1-methyl-1,2,3,4-tetrazol-5-yl sulfone (0.4 g) as colorless scales, m.p. 147°-149° C.
