A solution of 4-methyl-4-H-1,2,4-triazole-3-thiol (1.72 g, 15 mmol) and 3-bromopropan-1-ol (1.39 g, 10 mmol) in DMF (10 ml) containing potassium carbonate (1.57 g, 14 mmol) was heated at 40° C. for 30 minutes. The mixture was then partitioned between saturated ammonium chloride and ethyl acetate. The aqueous layer was evaporated to dryness and the residue was triturated with ethyl acetate and methylene chloride. The suspension was filtered and the filtrate was dried (MgSO4) and evaporated. The residue was purified by column chromatography eluting with methylene chloride/methanol (9/1) to give 3-((4-methyl-4H-1,2,4-triazol-3-yl)sulphanyl)propan-1-ol (510 mg, 30%).
