Procedure
To a solution (2S,3R,4R,5S,6R)-2-[3-(1-benzyl-1,2,3,4-tetrahydro-quinolin-7-ylmethyl)-4-isopropyl-phenyl]-6-hydroxymethyl-tetrahydro-pyran-3,4,5-triol (1.0 g, 1.0 mmol) in methanol (20 mL) was added 10% dry palladium on charcoal (200 mg) and conc. HCl (0.2 mL), and the mixture was stirred under hydrogen balloon pressure for 18 h. The reaction mixture was filtered through a celite bed which was washed with methanol and the filtrate was concentrated. The resulting residue was purified by preparative HPLC to furnish (2R,3S,4R,5R,6S)-2-Hydroxymethyl-6-[4-isopropyl-3-(1,2,3,4-tetrahydro-quinolin-7-ylmethyl)-phenyl]-tetrahydro-pyran-3,4,5-triol (320 mg).
