To a stirred solution of 6-[2-cyclopropyl-5-((3S,4R,5R,6R)-3,4,5-tris-benzyloxy-6-benzyloxymethyl-tetrahydro-pyran-2-yl)-benzyl]-chroman (650 mg) in THF (5 mL) was added 10% palladium charcoal activated (dry) (100 mg), methanol (5 mL), and conc. HCl (0.2 mL). The reaction mixture was stirred under hydrogen atmosphere (bladder pressure) overnight then filtered through a celite bed. The filtrate was concentrated and purified by preparative HPLC to furnish (2S,3R,4R,5S,6R)-2-(3-chroman-6-ylmethyl-4-cyclopropyl-phenyl)-6-hydroxymethyl-tetrahydro-pyran-3,4,5-triol (63 mg).
