Reaction Steps

To a mixture of 0.30 g of 4-acetyl-3-hydroxy-2-propylbenzyl chloride, 0.24 g of 2,5-dimercapto-1,3,4-thiadiazole, 0.20 g of anhydrous potassium carbonate and 4 ml of methyl ethyl ketone was added a catalytic amount of tetra-n-butylammonium bromide. The mixture was stirred at 60° C. for 1 hour. After the reaction solution was rendered neutral by adding diluted hydrochloric acid thereto, it was extracted with ethyl acetate. After the extract was dried over anhydrous magnesium sulfate, the solvent was distilled off The residue was recrystallized from isopropyl alcohol to give 0.20 g of 2-[(4-acetyl-3-hydroxy-2-propylbenzyl)thio]-5-mercapto-1,3,4-thiadiazole.
