3-(indolin-1-ylsulfonyl)benzoic acid (3) (200 mg, 0.66 mmol) and 6-methoxybenzo[d]thiazol-2-amine (99 mg, 0.55 mmol) using method C. The residue was purified using flash chromatography eluting with 0-40% EtOAc in hexanes. The resulting solid was triturated with dichloromethane/hexanes to give 3-(indolin-1-ylsulfonyl)-N-(6-methoxybenzo[d]thiazol-2-yl)benzamide as an off-white solid. Yield: 89 mg (35%). 1H-NMR: 8.57 (s, 1H), 8.37 (d, J=8 Hz, 1H), 8.01 (d, J=8.0 Hz, 1H), 7.77-7.66 (m, 2H), 7.63 (d, J=2.5 Hz, 1H), 7.53 (d, J=8.5 Hz, 1H), 7.22 (t, J=7.5 Hz, 1H), 7.16 (d, J=7.5 Hz, 1H), 7.07 (dd, J=8.5, 2.5, 1H), 6.99 (dt, J=7.5, 7.5, 1.0 Hz, 1H), 4.02 (t, J=8.5 Hz, 2H), 3.83 (s, 3H), 2.92 (t, J=8.5 Hz, 2H).
