Procedure
(S)-2-Amino-3-(2,4-dichloro-phenyl)-propionic acid was treated as in EXAMPLE 2, Part A, to produce (S)-2-amino-3-(2,4-dichloro-phenyl)-propionic acid methyl ester hydrochloride as a white solid. This ester was coupled with 4-bromo-2-(2,6-difluoro-benzenesulfonylamino)-benzoic acid as in EXAMPLE 1, Part C. The resulting methyl ester was hydrolyzed as in EXAMPLE 2, Part E, to afford title compound. HPLC: RT=10.26 min. MS (ESI−): mass calcd. for C22H15BrCl2F2N2O5S, 608.2; m/z found, 607 [M−H]−. 1H NMR (400 MHz, CDCl3): 11.36 (s, 1H), 7.87 (d, J=1.8, 1H), 7.52-7.44 (m, 1H), 7.39 (d, J=1.6, 1H), 7.27-7.25 (m, 1H), 7.25-7.22 (m, 1H), 7.18-7.15 (m, 1H), 6.97 (t, J=8.7, 2H), 6.79 (d, J=7.7, 1H), 5.05-5.00 (m, 1H), 3.50 (dd, J=14.2, 5.5, 1H), 3.29 (dd, J=14.2, 8.1, 1H).
