3-(indolin-1-ylsulfonyl)benzoic acid (3) (100 mg, 0.33 mmol) was treated with 4-(pyridin-2-yl)thiazol-2-amine (49 mg, 0.28 mmol) using method C. The residue was purified using flash chromatography eluting with 75-100% EtOAc in hexanes. The resulting solid was triturated with diethyl ether to give 3-(indolin-1-ylsulfonyl)-N-(4-(pyridin-2-yl)thiazol-2-yl)benzamide as a white solid. Yield: 17 mg (13%). 1H-NMR: 8.65-8.61 (m, 1H), 8.60-8.58 (m, 1H), 8.38 (dt, J=8.0, 1.0, 1.0 Hz, 1H), 8.05-7.99 (m, 2H), 7.95-7.88 (m, 2H), 7.74 (t, J=8.0 Hz, 1H), 7.53 (d, J=8.5 Hz, 1H), 7.38-7.33 (m, 1H), 7.22 (t, J=8.0 Hz, 1H), 7.16 (d, J=7.5 Hz, 1H) 6.99 (dt, J=7.5, 7.5, 1.0 Hz, 1H), 4.03 (t, J=8.5 Hz, 2H), 2.93 (t, J=8.5 Hz, 2H).
