3-(indolin-1-ylsulfonyl)benzoic acid (3) (200 mg, 0.66 mmol) and 3-methoxyaniline (68 mg, 0.55 mmol) using method C. The residue was purified using flash chromatography eluting with 0-30% EtOAc in hexanes. The resulting solid was triturated with dichloromethane/hexanes to give 3-(indolin-1-ylsulfonyl)-N-(3-methoxyphenyl)benzamide as an off-white solid. Yield: 94 mg (42%). 1H-NMR: 8.34 (s, 1H), 8.22 (d, J=8.0 Hz, 1H), 7.99 (d, J=8.0 Hz, 1H), 7.72 (t, J=8.0 Hz, 1H), 7.51 (d, J=8.0 Hz, 1H), 7.42 (t, J=2.0 Hz, 1H), 7.32 (d, J=8.5 Hz, 1H), 7.27 (t, J=8.0 Hz, 1H), 7.21 (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), 6.71 (ddd, J=8.0, 2.5, 1.0 Hz, 1H), 3.98 (t, J=8.5 Hz, 2H), 3.32 (s, 3H), 2.92 (t, J=8.5 Hz, 2H)
