Reaction Steps

To 1.2 g of 1-dimethylearbamoyl-3-t-butyl-5-carboethoxyrmthylthio-1H-1,2,4-triazole (the compound of Example 2) in 20 ml of THF was added 4 ml of 12 M HC1. After stirring for 48 h at 20° C. the reaction mixture was partitioned between ether and water, the ether layer was extracted with dilute NAOH and the resulting aqueous layer was acidified and extracted with fresh ether. The resulting ether layer was dried over magnesium sulfate, filtered and evaporated under vacuum to yield 1-dimethylcarbamyl-3-t-butyl-5-carboxymethylthio-1H-1,2,4-triazole as an oil.
