Procedimiento

1-Ethylpropylamine (0.1 mole) and water (50 ml) are charged into a glass reaction vessel fitted with a mechanical stirrer and thermometer. The solution is cooled to 20° C. and stirred while 2-acetamido-5-chlorosulfonyl-1,3,4-thiadiazole (0.1 mole) is added slowly while holding the reaction temperature between 0° C. and 20° C. At the conclusion of the addition, stirring is continued for a period of about 2 hours at room temperature. The reaction mixture is then neutralized with 6 N hydrochloric acid. Solids are filtered out, water washed and dried to yield the desired product 2-acetamido-5-[N-(1-ethylpropyl)aminosulfonyl]-1,3,4-thiadiazole.
