反応手順

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-fluoro-1H-indol-1-yl)-2-methylpropanoic acid (66 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 12.76 (s, 1H), 7.71 (d, J=8.5 Hz, 2H), 7.66 (s, 1H), 7.27-6.91 (m, 5H), 6.90-6.82 (m, 2H), 6.68 (d, J=3.0 Hz, 1H), 4.23 (s, 1H), 3.87 (bs, 1H), 3.57 (bs, 1H), 3.42-3.35 (m, 1H), 3.06 (s, 1H), 2.89 (s, 1H), 1.81 (d, J=8.3 Hz, 6H). LC/MS (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA), m/z: M+1 obs=542.5; tR=2.91 mm.
