To a solution of methyl 3-(4-(4′-((5-(tert-butyl)-1,3,4-oxadiazol-2-yl)amino)-[1,1′-biphenyl]-4-yl)-7-oxabicyclo[2.2.1]heptan-1-yl)propanoate (100 mg, 0.21 mmol) in THF (3.4 mL) and methanol (0.85 mL) was added 1N NaOH solution (0.63 mL, 0.63 mmol) and the reaction was let stir at rt for 2 h. The resulting yellow reaction mixture was partially concentrated by rotary revaporation (rt water bath) to remove THF. The resulting yellow mixture was diluted with methanol, filtered and purified on preparative HPLC (10-50% acetonitrile:5 mM NH4OH) and lyophilized to afford 83 mg (86%) of the title compound as a white solid. 1H NMR (400 MHz, DMSO-d6): δ ppm 1.36 (s, 9H), 1.56-1.82 (m, 6H), 2.01-2.10 (m, 2H), 2.10-2.19 (m, 2H), 2.30-2.39 (m, 2H), 7.43 (d, J=8.6 Hz, 2H), 7.60 (d, J=8.6 Hz, 2H), 7.62-7.67 (m, 4H) 10.51 (br. s., 1H). 13C NMR (100 MHz, DMSO-d6): δ ppm 174.5, 165.9, 159.5, 141.7, 138.3, 138.2, 133.1, 127.1, 125.8, 125.4, 117.1, 86.1, 85.5, 37.9, 34.9, 31.7, 30.2, 30.1, 27.8. ESI-MS m/z: 462.1 [M+H]+, retention time 1.13 min (condition E). HR/MS [M+H]+: found 462.2371. calc. 462.2393. RT: 1.96 (Condition L).
