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

A solution of ethyl 2,4-dimethyl-1,3-thiazole-5-carboxylate (5.0 g) in THF (50 ml) was added dropwise to a solution of aluminum lithium hydride (1.1 g) in THF (150 ml) under ice-cooling. After stirred at room temperature for 4 hours, water (1.1 ml), 15% sodium hydroxide solution (1.1 ml) and water (3.3 ml) were added thereto, and the mixture was stirred for 10 minutes. The mixture was filtered with Celite, and washed with methanol. The solvent was removed under reduced pressure, and the resulting residue was purified with silica gel column chromatography (hexane/ethyl acetate=1/2) to give (2,4-dimethyl-1,3-thiazol-5-yl)methanol (2.0 g).
