Reaktionsschritte

In a similar manner to Step 2 of Example 440, 4-chloro-5-(3-chloropropoxy)-7-[1-(tert-butoxycarbonyl)-5-(piperidin-1-ylmethyl)indol-2-yl]isoindolinone (97.6 mg, 0.170 mmol) was dissolved in N,N-dimethylacetoamide (1.0 mL), and the solution was treated with 4-piperidine methanol (0.196 mL, 1.70 mmol). 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-(4-hydroxymethylpiperidin-1-yl)propoxy]-7-[1-(tert-butoxycarbonyl)-5-(piperidin-1-ylmethyl)indol-2-yl]isoindolinone (87.2 mg, yield 79%).
