Aluminium lithium hydride → (4-Ethylthiazol-5-yl)methanol

Participants

Reaction Conditions

Reaction Steps

To a 0° C. mixture of lithium aluminum hydride (1.2 g, 31.2 mmol) in anhydrous THF (30 mL) was slowly added a solution of ethyl 4-ethyl-1,3-thiazole-5-carboxylate (3.19 g, 15.6 mmol) in anhydrous THF (40 mL). The reaction mixture was stirred at 0° C. for 1.5 hours. The reaction was quenched with 5 N NaOH. Water (100 mL) and EtOAc (100 mL) were added. The mixture was stirred for 30 minutes. The solid material was removed by filtration. The organic layer was recovered. The aqueous layer was extracted with EtOAc (1×100 mL). The combined organic extracts were dried over MgSO4, filtered, evaporated, and dried in vacuo, affording (4-ethyl-1,3-thiazol-5-yl)methanol (1.77 g, 79% yield). The product was used without further purification.
