反応手順

Synthesized according to general procedure 9, method B. The reaction was set up with (S)-4-(3-methylpiperazin-1-yl)-N-(thiazol-2-yl)benzenesulfonamide (250 mg, 0.74 mmol), 2-(5-fluoro-1H-indol-1-yl)acetic acid (143 mg, 0.74 mmol), HATU reagent (281 mg, 0.74 mmol), sodium bicarbonate (93 mg, 1.11 mmol), and DMF/CH2Cl2-1/1 (4.0 mL) to obtain the desired amide as a white solid (200 mg, 0.39 mmol, 53% yield). 1H NMR (400 MHz, DMSO-d6) δ(mixture of rotamers) 7.63-7.59 (m, 2H), 7.35 (s, 1H), 7.30 (dd, J=2.5, 9.9 Hz, 2H), 7.21 (d, J=4.6 Hz, 1H), 7.00 (s, 1H), 6.95 (td, J=9.2, 3.9 Hz, 2H), 6.76 (d, J=4.5 Hz, 1H), 6.43 (d, J=3.0 Hz, 1H), 5.41-5.04 (m, 2H), 4.52 (s, ½H), 4.38 (s, ½H), 4.21-4.05 (m, ½H), 3.93-3.82 (m, ½H), 3.81-3.48 (m, 3H), 1.33 (s, 1.5H), 1.14 (s, 1.5H). LC/MS (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA), m/z: M+1 obs=514.5; tR=3.07 min.
