To a solution of 1,2,3-thiadiazol-4-ylmethanol methanesulfonate (0.90 g, 4.6 mmol) in tetrahydrofuran (9 mL) was added an aqueous solution (2 mL) of sodium thiolacetate [prepared from thiolacetic acid (0.38 mL, 5.3 mmol) and sodium bicarbonate (0.445 g, 5.3 mmol)]. The resulting mixture was stirred at 23° C. for 1 h and diluted with ether (75 mL). The organic solution was washed with water (3×3 mL), dried (MgSO4) and concentrated. The crude mixture was purified by chromatography (silica gel column: 1.4×19 cm) with 50% ether in hexane as eluting solvent to give 0.60 g (75%);
