To a solution of 4-(4-methyl-piperazin-1-ylmethyl)-N-[3-(2-oxo-2,3-dihydro-1H-indol-5-ylamino)-phenyl]-benzamide (23 mg, 0.05 mmol) in ethanol (2 ml) is added 1H-pyrrole-2-carbaldehyde (16 mg, 0.17 mmol) and 2 drops of piperidine. The reaction is refluxed for 12 hours and then concentrated. The desired compound after HPLC purification: 1H NMR (DMSO-d6) δ 2.44-2.52 (m, 2H), 2.79 (s, 3H), 2.98-3.10 (m, 2H), 3.18-3.22 (m, 2H), 3.38-3.42 (m, 2H), 3.77 (s, 2H), 6.32-6.36 (m, 1H), 6.61-6.69 (m, 111), 6.81-6.82 (m, 2H), 6.92 (dd, 1H, J=8.8 Hz, J2=1.6 Hz), 7.12-7.18, (m, 2H), 7.34 (s, 1H), 7.46 (dd, 2H, J=4.8 Hz, J2=1.6 Hz), 7.48 (s, 2H), 7.69 (s, 1H), 7.93 (d, 2H, J=8.0 Hz), 8.01 (s, 1H), 10.09 (s, 1H), 10.78 (s, 1H), 13.39 (s, 1H); LC-MS: 533.2 (MH+).
