Reaction Steps

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), 2-(6-(trifluoromethyl)-1H-indol-1-yl)acetic acid (71 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 (55 mg, 0.10 mmol, 34% yield). 1H NMR (400 MHz, DMSO-d6) δ 12.78 (s, 1H), 7.91 (s, 1H), 7.85 (d, J=8.4 Hz, 2H), 7.75 (d, J=8.3 Hz, 1H), 7.58 (dd, J=5.1, 8.4 Hz, 2H), 7.52-7.48 (m, 1H), 7.32-7.27 (m, 2H), 6.85 (d, J=4.6 Hz, 1H), 6.61 (d, J=2.9 Hz, 1H), 5.40 (d, J=9.8 Hz, 2H), 4.49 (s, 1H), 4.22 (s, 1H), 4.01 (s, 2H), 3.81 (s, 2H). LC/MS (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA), m/z: M+1 obs=564.4; tR=3.17 min.
