Versuchsvorschrift
Following the procedure in Example 1: step d, 6-(3-{3′-[5-(tert-butoxycarbonylamino-imino-methyl)-2-methylsulfanyl-thiophene-3-sulfonyl]-2-methyl-biphenyl-4-yl}-ureido)-hexanoic acid ethyl ester ((Example 311: step a) 12 mg) was treated with 1:1 TFA/DCM. Purification by HPLC yielded the product (8.3 mg) as a white solid. 1H-NMR (CD3OD): δ 8.31 (s, 1H), 7.97 (m, 1H), 7.94 (m, 1H), 7.65 (m, 2H), 7.29 (m, 2H), 7.09 (m, 1H), 4.10 (q, 2H, 7.2 Hz), 3.20 (t, 2H, 7.0 Hz), 2.71 (s, 3H), 2.33 (t, 2H, J=7.3 Hz), 2.19 (s, 3H), 1.65 (m, 2H), 1.55 (m, 2H), 1.40 (m, 2H), 1.23 (t, 3H, J=7.2 Hz). ESI-MS (m/z): Calcd. for C28H34N4O5S3 (M+H): 603.2; found: 603.2.
