PROCEDURE

实验过程

To (S)-3-methyl-2-{4′-[(5-chloro-benzothiazole-2-carbonyl)-amino]-biphenyl-4-sulfonylamino}-butyric acid tert-butyl ester (30 mg) was added 3 mL of TFA/CH2Cl2 (1:1). The solution was stirred at room temperature for 3 h. The solvents were removed under vacuum and the residue was triturated with ether. Filtration gave 105 mg of (S)-3-methyl-2-{4′-[(5-chloro-benzothiazole-2-carbonyl)-amino]-biphenyl-4-sulfonylamino}-butyric acid as yellow solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 0.79-0.88 (m, 6 H) 1.85-2.07 (m, 1 H) 3.56 (dd, 1 H) 7.70 (dd, 1 H) 7.76-7.94 (m, 6 H) 8.03-8.12 (m, 3 H) 8.26 (d, 1 H) 8.35 (d, 1 H) 11.36-11.40 (m, 1 H).
