Procedure

Synthesized according to general procedure 14, method A. The reaction was set up with 4-(2-oxopiperazin-1-yl)-N-(thiazol-2-yl)benzenesulfonamide (100 mg, 0.29 mmol), 3-(5-chloro-1H-indol-1-yl)propanoic acid (65 mg, 0.29 mmol), HATU reagent (220 mg, 0.58 mmol), sodium bicarbonate (74 mg, 0.87 mmol), and DMF/CH2Cl2-1/1 (0.50 mL) to obtain the desired amide as a white solid (50 mg, 0.10 mmol, 32% yield). 1H NMR (400 MHz, DMSO-d6) δ 12.77 (s, 1H), 7.81 (d, J=8.6 Hz, 2H), 7.58-7.53 (m, 2H), 7.49-7.44 (m, 3H), 7.26 (d, J=4.6 Hz, 1H), 7.13 (dd, J=2.1, 8.7 Hz, 1H), 6.84 (d, J=4.6 Hz, 1H), 6.42-6.41 (m, 1H), 4.47-4.40 (m, 2H), 4.18 (s, 1H), 4.15 (s, 1H), 3.77-3.74 (m, 4H), 2.94-2.90 (m, 2H). LC/MS (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA), m/z: M+1 obs=544.2; tR=3.00 min.
