Water → (Dichloro-1,3-thiazol-5-yl)methanol

To a 0° C. solution of 2,4-dichloro-1,3-thiazole-5-carbaldehyde (1.0 g, 5.5 mmol) in anhydrous methanol (45 mL) was added sodium borohydride (340 mg, 9.0 mmol). The reaction mixture was stirred at room temperature overnight. Water (50 mL) was added and the methanol was evaporated. The resultant mixture was extracted with EtOAc (2×50 mL). The organic extracts were combined, dried over MgSO4, filtered, evaporated, and dried in vacuo, to afford (2,4-dichloro-1,3-thiazol-5-yl)methanol (850 mg, 84% yield). The product was used without further purification.
