Versuchsvorschrift

To a solution of (2,4-dichloro-1,3-thiazol-5-yl)methanol (850 mg, 4.6 mmol) in anhydrous dichloromethane (40 mL) was added dropwise phosphorus tribromide (850 μL, 9.2 mmol). The mixture was stirred at room temperature for 3 hours. The solvent was evaporated. The residue was dried in vacuo, affording 5-(bromomethyl)-2,4-dichloro-1,3-thiazole. The product was used without further purification.
