Reaction Steps

To a tetrahydrofuran (0.8 mL) and methanol (0.2 mL) solution of (1S)-1,5-anhydro-2,3,4,6-tetra-O-benzyl-1-[2-(benzyloxy)-5-[4-[2-(1,3-dioxo-1,3-dihydro-2H-isoindole-2-yl)ethoxy]-2-methylbenzyl]-4-methylphenyl]-D-glucitol (60 mg, 0.059 mmol) was added hydrazine monohydrate (30 mg, 0.59 mmol), and the reaction mixture was stirred at 65° C. for an hour. After the mixture was cooled to room temperature, a 2 M aqueous solution of sodium hydroxide was added thereto, and the resulting mixture was extracted with ethyl acetate. The organic layer was washed with brine, and dried with anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to obtain the title compound quantitatively.
