Hydrochloric Acid → HCID 178524402, compound

Participants

Reaction Steps

To a mixture of 1.5 g of 2,5-dimercapto-1,3,4-thiadiazole, 2.76 g of anhydrous potassium carbonate and 10 ml of N,N-dimethylformamide was added 1 g of p-(bromomethyl)benzoic acid followed by stirring at room temperature for 3 hours. The reaction mixture was diluted with 30 ml of water, made acidic with diluted hydrochloric acid and, extracted with ethyl acetate. The extract was washed with water, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was applied to silica gel column chromatography. Elution with a mixture of toluene-ethyl acetate (1:1) gave 400 mg of p-[(5-mercapto-1,3,4-thiadiazol-2-yl)thiomethyl]benzoic acid.
