Procedure
To a solution of N-(2-oxo-2,3-dihydro-1H-indol-6-yl)-benzamide (80 mg, 0.32 mmol) and 5-formyl-2,4-dimethyl-1H-pyrrole-3-carboxylic acid (53 mg, 0.32 mmol) in ethanol (8 ml) is added 4 drops of piperidine. It is stirred at 80° C. for 20 hours and then cooled to room temperature. The precipitate is collected by vacuum filtration, washed with a small amount of cold ethanol to give crude 5-(6-benzoylamino-2-oxo-1,2-dihydro-indol-3-ylidenemethyl)-2,4-dimethyl-1H-pyrrole-3-carboxylic acid. This carboxylic acid (20 mg, 0.050 mmol) is then dissolved in DMF (1 ml). To this reaction is also added N, N-diethylethylenediamine (17 mg, 0.15 mmol), N,N-diisopropylethylamine (19 mg, 0.15 mmol) and HATU (23 mg, 0.061 mmol). It is stirred for 2 hours and concentrated. The desired compound is obtained after HPLC purification: 1H NMR (DMSO-d6) δ 1.24 (t, 6H, J=7.2 Hz), 2.43 (s, 3H), 2.47 (s, 3H), 3.20-3.24 (m, 6H), 3.57 (q, 2H, J=5.4 Hz), 7.38 (d, 1H, J=6.6 Hz), 7.53 (t, 2H, J=7.2 Hz), 7.56 (s, 1H), 7.58-7.61 (m, 2H), 7.73-7.77 (m, 2H), 7.96 (d, 2H, J=7.8 Hz), 9.32 (s, 1H), 10.27 (s, 1H), 10.97 (s, 1H), 13.60 (s, 1H); LC-MS: 500.2 (MH+).
