実験手順
To a solution of [4-(propan-2-yl)-1,3-thiazol-5-yl]methanol (800 mg, 5.1 mmol) in anhydrous dichloromethane (35 mL) was added tribromophosphane (520 μL, 5.5 mmol). The mixture was stirred at room temperature for 1.5 hours. Dichloromethane was evaporated. The residue was dried in vacuo, affording 5-(bromomethyl)-4-(propan-2-yl)-1,3-thiazole. The crude product was used without further purification.
