1-Bromohexane → Sbb043676

Participants

Reaction Steps

In 190 ml of ethanol and 240 ml of water, 81.5 g of 2-amino-5-mercapto-1,3,4-thiadiazole and 26.9 g of sodium hydroxide were added. To this solution, 99 g of 1-bromohexane was added and the resulting mixture was warmed to 60°~70° C. and stirred for 2 hours. After cooling, water was added to the reaction mixture, and the resulting solution was filtered. The residue was washed with water and dried under reduced pressure. The dried residue was recrystallized from an ethanol/hexane mixture, and thus 100.5 g of 2-amino-5-hexylthio-1,3,4-thiadiazole was obtained.
