Vorschrift

4-Chloro-5-(3-chloropropoxy)-7-[1-(tert-butoxycarbonyl)-5-(piperidin-1-ylmethyl)indol-2-yl]isoindolinone (90.4 mg, 0.158 mmol) was dissolved in N,N-dimethylacetoamide (1.0 mL), and the solution was added with 2-(ethylamino)ethanol (0.321 mL, 2.37 mmol), followed by stirring at 90° C. for 72 hours. The reaction mixture was added with water. The obtained solid was collected by filtration and washed with water, followed by drying under reduced pressure to obtain 4-chloro-5-[3-[N-ethyl(2-hydroxyethyl)amino]propoxy]-7-[1-(tert-butoxycarbonyl)-5-(piperidin-1-ylmethyl)indol-2-yl]isoindolinone (79.8 mg, yield 81%).
