To a solution of 3.12 g (0.02 mol) of 5-mercapto-1-methyltetrazole sodium salt hydrate in 60 ml of absolute ethanol was added dropwise, 2.06 g (0.2 mol) of chloroacetone. After stirring for 20 hours at room temperature, the ethanol was evaporated in vacuo. The residue was dissolved in methylene chloride and was washed with water and then brine prior to drying over Na2SO4. Evaporation of the methylene chloride solution gave 1-methyl-5-acetonylthiotetrazole that was purified by flash chromatography on silica gel to yield 0.94 g of the 5-acetonylthio-1-methyltetrazole product.
