Reaction Steps

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 (87.1 mg, 0.152 mmol) was dissolved in N,N-dimethylacetoamide (0.9 mL), and the solution was treated with N-methylpiperazine (0.138 mL, 1.58 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-methylpyperazin-1-yl)propoxy]-7-[1-(tert-butoxycarbonyl)-5-(piperidin-1-ylmethyl)indol-2-yl]isoindolinone (59.5 mg, yield 68%).
