To a round bottom flask containing methyl 2-(4-(4′-nitrobiphenyl-4-yl)-2-oxabicyclo[2.2.2]octan-1-yl)acetate (716 mg, 1.88 mmol) was added Pd(OH)2 on activated carbon (395 mg, 2.82 mmol). EtOAc (15 ml) and MeOH (3 ml) were added and the mixture was stirred under 1 atm. of hydrogen at room temperature for 2 hours. The resulting mixture was filtered through a pad of celite and concentrated to afford a crude residue. Column purification affords the title compound as off-white solid after drying (595 mg, 90% yield). LC/MS, ESI-MS(+): 352.3, RT: 1.29 (Condition E).
