Reaction Steps
To a solution of (2R,3R,4R,5S,6S)-2-(acetoxymethyl)-6-(4-cyano-3-(4-(2-oxoethoxy)benzyl)phenyl)tetrahydro-2H-pyran-3,4,5-triyl triacetate (100.0 mg, 0.17 mmol) in ethanol (4 mL) under nitrogen atmosphere, was added pyridine (0.07 mL, 0.86 mmol) and O-methylhydroxylamine hydrochloride (28.7 mg, 0.34 mmol). The reaction mixture was heated at 80° C. for 2 h. After completion of the reaction as confirmed by TLC, the solvent was evaporated. The crude compound was diluted with ethyl acetate (40 mL). The organic layer was separated, washed with 5% HCl (10 mL), water (10 mL), dried over Na2SO4 and concentrated in vacuo to afford crude product which was purified by column chromatography (silica gel, 1:49 EtOAc:Pet Ether) to afford title compound (60 mg, 43%) as solid.
