Potassium Carbonate → HCID 13061942, compound

Participants

Reaction Steps

1-Methyl-5-mercapto-1,2,3,4-tetrazole (1.2 g) is dissolved in acetone (50 ml). To the solution are added 2-(3-chloropropyl)thiopyridine (2.0 g) and potassium carbonate (1.5 g) and the mixture is refluxed for 4 hours. Acetone is distilled off and water is added to the residue. The mixture is extracted with chloroform. The chloroform solution is washed with saturated aqueous sodium chloride and dried over magnesium sulfate. Chloroform is distilled off and the residue is purified by column chromatography (Kieselgel 60). The column is eluted with chloroform-methanol and the product is recrystallized from ethanol to obtain 1-methyl-5-[2-(2-pyridyl)thioethyl]thio-1,2,3,4-tetrazole (1.5 g) as colorless prisms, m.p. 77°-79.5° C.
