Procedure

A solution of 5-{[(tert-butyldimethylsilyl)oxy]methyl}-4-ethenyl-1,3-thiazole (763 mg, 3.0 mmol) and a tetrabutylammonium fluoride solution (1M in THF; 4 mL, 4.0 mmol) in anhydrous THF (30 mL) was stirred at room temperature for 1.5 hours. The solvent was evaporated, and the residue was treated with EtOAc (50 mL). The solution was extracted with water (3×50 mL) and brine (1×50 mL), dried over MgSO4, filtered, and evaporated. The residue was dried in vacuo, affording (4-ethenyl-1,3-thiazol-5-yl)methanol (370 mg, 87%). The product was used without further purification.
