Reaction Steps

A small screw cap test tube was charged with N-[3-(3-Hydroxymethylene-2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-acetamide (as prepared in Example 40, 100 mg, 0.310 mmol) and THF (2 mL). To the resulting solution was added 4-(4-methyl-piperazin-1-yl)-phenylamine (65.27 mg, 0.341 mmol), and the mixture was stirred for 24 h at 65° C. Subsequently, the reaction mixture was cooled to room temperature and concentrated in vacuo. The crude residue was purified over silica (5% MeOH/CHCl3) providing the title compound in 53% yield (81 mg, 0.163 mmol).
