Reaction Steps

Into a 25-mL round-bottom flask, was placed ethyl 3-[4-(1,1-difluoroethyl)phenyl]-5-(trifluoromethyl)-1,2-thiazole-4-carboxylate (450 mg, 1.23 mmol, 1.00 equiv), tetrahydrofuran (4 mL). This was followed by the addition of LiAlH4 (2.5 mL) dropwise with stirring at 0° C. The resulting solution was stirred for 15 min at room temperature (20 degree). The reaction was then quenched by the addition of 5 mL of water. The resulting solution was extracted with 5×5 mL of ethyl acetate and the organic layers combined. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (16:84). This resulted in 110 mg (28%) of [3-[4-(1,1-difluoroethyl)phenyl]-5-(trifluoromethyl)-1,2-thiazol-4-yl]methanol as a yellow solid. Mass spectrum (ESI, m/z): Calcd. for C13H10F5NOS, 324.0 (M+H). found 324.0.
