Hydrogen chloride in dioxan (4.0 M, 5 mL, 24 mmol) was added to a solution of tert-butyl((3-((3-(4-((1,3-dioxolan-2-yl)methyl)phenyl)-1,2,4-oxadiazol-5-yl)methoxy)phenyl)(phenyl)methyl)carbamate (1.01 g, 1.85 mmol) in methanol (5 mL), and the resultant solution was stirred at ambient temperature for 2 hours. The solvent was evaporated at reduced pressure, and the residue was loaded onto an SCX-2 cartridge. The cartridge was eluted with methanol (eight column volumes) followed by ammonia/methanol. Fractions containing the product were combined and evaporated at reduced pressure to afford the title compound (0.796 g, 96%).
