Procedure

To a vial containing 2-chloro-3-[5-chloro-3-(4-chloro-3-trifluoromethylbenzene-sulfonylamino)-pyridine-2-carbonyl]benzoic acid (24 mg, 0.04 mmol) were added HATU (75 mg, 0.2 mmol), DMF (1 mL), a 2.0 M solution of MeNH2 in THF (0.3 mL, 0.6 mmol), and (i-Pr)2NEt (35 L, 0.2 mmol). The solution was maintained at room temperature for 15 h. EtOAc (20 mL) was added, and the organic phase washed with saturated aqueous NaCl (2×10 mL) and dried over MgSO4. The volatiles were removed in vacuo, and the resulting residue was purified by preparative HPLC (20→95% gradient of MeCN—H2O with 0.1% TFA). The pure fractions were lyophilized to afford the title compound (5 mg, 5% yield): HPLC retention time=2.69 minutes. MS (ES) [M+H]+ expected 566.0. found 565.9. 1H NMR (400 MHz, CDCl3) δ 10.98 (s, 1H), 8.17-8.21 (m, 3H), 8.00 (dd, J=2.4, 8.8 Hz, 1H), 7.65-7.69 (m, 2H), 7.41 (t, J=7.2 Hz, 1H), 7.30 (dd, J=1.6, 7.2 Hz, 1H), 6.01 (bs, 1H), 3.01 (d, J=5.2 Hz, 3H).
