1,3-Dibromopropane → HCID 12818274, compound

Participants

Reaction Steps

1-Methyl-5-mercapto-1,2,3,4-tetrazole (4.6 g) and 1,3-dibromopropane (4 g) are dissolved in acetone (50 ml). To the mixture is added potassium carbonate (5.5 g), and the mixture is refluxed for 3 hours. After acetone is distilled off, water is added to the residue, and the precipitated crystals are separated by filtration and recrystallized from ethanol to give 1-methyl-5-[3-(1-methyl-1,2,3,4-tetrazol-5-yl)thiopropyl]thio-1,2,3,4-tetrazole (3.6 g) as colorless prisms, m.p. 141.5°-143.5° C.
