実験手順
A solution of dichloromethane/trifluoroacetic acid (1/1) [2 mL] was added to {3′-[5-(tert-butoxycarbonylamino-imino-methyl)-2-methylsulfanyl-thiophene-3-sulfonyl]-2,6-dimethyl-biphenyl-4-yloxy}-acetic acid tert-butyl ester (0.020 g, 0.030 mmol) [example 215, step a] at room temperature and stirred for 1 hour. The reaction mixture was evaporated and purified via reverse-phase HPLC [acetonitrile/water (0.01% TFA)] to give the title compound (0.011 g, 75%) as a solid. 1H-NMR (MeOD): δ 8.36 (s, 1H), 8.01 (md, 1H, J=7.6 Hz), 7.81 (m, 1H), 7.72 (m, 1H), 7.51 (d, 1H, J=7.6 Hz), 7.26 (d, 1H, J=8.0 Hz), 6.74 (s, 2H), 4.67 (s, 2H), 2.73 (s, 3H), 1.96 (s, 6H). ESI-MS (m/z): Calcd. for C22H22N2O5S3: 490.07; found: 491.2.
