6-(2-chloro-5-((2S,3R,4R,5S,6R)-3,4,5-tris(benzyloxy)-6-((benzyloxy)methyl) tetrahydro-2H-thiopyran-2-yl)benzyl)-2,3-dihydrobenzo[b][1,4]dioxine (126, 204 mg, 0.26 mmol) in dichloromethane (5 mL) reacted with BCl3 (1.5 mL) at 0° C. The reaction mixture was stirred at 0° C. for 0.5 h. After quenching the reaction with methanol, solvent was evaporated under a reduced pressure. Purification by reverse phase preparative HPLC (Gilson®, SunFire™ Prep, 5 to 50% acetonitrile in water gradient) provided the title compound (E047, 13 mg, 12% yield) as a white solid.
