Reaction Steps

To a mixture of (2S,3R,4R,5S,6R)-2-[4-chloro-3-(4-ethoxy-benzyl)-phenyl]-6-hydroxymethyl-tetrahydro-pyran-3,4,5-triol (7.0 g, 17.1 mmole, prepared according to procedure described in J. Med. Chem. 2008; 51 (5); 1145-1149), trityl chloride (5.2 g, 18.8 mmole) in pyridine (50 mL) was added at room temperature and heated at 80° C. for 18 hrs. The excess pyridine was evaporated, reaction mixture was diluted with water (250 mL), washed with 1N dil. HCl (50 mL) extracted with dichloromethane (2×200 mL). The crude product obtained after the removal of solvent was purified using silica gel column chromatography (0.5% methanol in DCM) to furnish 9.8 g of (2S,3R,4R,5S,6R)-2-[4-Chloro-3-(4-ethoxy-benzyl)-phenyl]-6-trityloxymethyl-tetrahydro-pyran-3,4,5-triol.
