Water → 2,4-Dibromothiazole-5-methanol

Participants

Reaction Steps

To a 0° C. solution of 2,4-dibromo-1,3-thiazole-5-carbaldehyde (3.38 g, 12.3 mmol) in anhydrous methanol (130 mL) was added sodium borohydride (600 mg, 15.9 mmol). The reaction mixture was stirred at room temperature for 3 hours. Water (100 mL) was added, and the mixture was evaporated. The resultant residue was extracted with EtOAc (3×100 mL). The organic extracts were combined, washed with brine (2×100 mL), dried over MgSO4, filtered, evaporated, and dried in vacuo, affording (2,4-dibromo-1,3-thiazol-5-yl)methanol (2.64 g, 77%). The product was used without further purification.
