Reaction Steps

To a solution of 2-[5-(2,6-dimethylpyrid-4-ylmethoxycarbonylamino)-6-oxo-2-(2-thienyl)-1,6-dihydro-1-pyridinyl]-N-(3,3,3-trifluoro-1-isopropyl-2-pivaloyloxypropyl)acetamide (1.44 g) in tetrahydrofuran (10 mL) and methanol (10 mL) was added a solution of lithium hydroxide monohydrate (0.92 g) in water (20 mL). The resulting solution was stirred for 2 h, diluted with saturated ammonium chloride (30 mL), and extracted with ethyl acetate. The ethyl acetate solution was dried and evaporated. The resulting material was chromatographed, eluting with ethyl acetate, to provide the alcohol (0.39 g) as a yellow foam; TLC: Rf =0.24, ethyl acetate; MS: m/z=568(M+1).
