Reaction Steps
To a suspension of 4-(4-ethyl-piperazin-1-ylmethyl)-N-[3-(2-oxo-2,3-dihydro-1H-indol-6-ylamino)-phenyl]-3-trifluoromethyl-benzamide (200 mg, 0.372 mmol) in EtOH (10 mL) are added pyrrole-2-carboxaldehyde (42 mg, 0.446 mmol) and piperidine (74 μL, 0.74 mmol). The mixture is heated at 80° C. for 2 hours. All the solvent is evaporated to dryness. The crude is recrystallized in EtOH to give 136 mg of the desired compound: 1H NMR (400 MHz, DMSO) δ 10.74 (s, 1 H), 10.34 (s, 1 H), 8.37 (s, 1 H), 8.18-8.24 (m, 2 H), 7.92 (d, 1 H); 7.67 (s, 1 H), 7.46-7.50 (t, 2 H), 7.24-7.28 (m, 3 H), 6.84 (d, 1 H), 6.76 (s, 1 H), 6.72 (m, 1 H), 6.67 (d, 1 H), 6.29-6.31 (m, 1 H), 3.69 (s, 2 H), 3.30 (s, 2 H), 2.30-2.48 (m, 8H), 1.00 (t, 3H); LC-MS: 615.3 (MH+).
