Reaction Steps

In 185 ml of ethanol and 185 ml of water, 68.0 g of 2-amino-5-mercapto-1,3,4-thiadiazole and 22.4 g of sodium hydroxide were added. To this mixture, 84.6 g of 1-bromoheptane was added, and the resulting mixture was warmed to 60° C. and stirred for 2 hours. After cooling, water was added and the mixture was filtered. The residue was washed with water, dried under reduced pressure, and recrystallized from an ethanol/hexane mixture. Thus 90.2 g of 2-amino-5-heptylthio-1,3,4-thiadiazole was obtained.
