Procedure

In a similar manner to Step 2 of Example 6, 4-[3-(tert-butoxycarbonylamino)propoxy]-7-[1-(tert-butoxycarbonyl)-5-formylindol-2-yl]isoindolinone (104 mg, 0.189 mmol) was dissolved in acetonitrile (5.2 mL), and the solution was treated with 1-(2-hydroxyethyl)piperazine (98 mg, 0.756 mmol), acetic acid (0.216 mL, 3.78 mmol) and sodium triacetoxyborohydride (160 mg, 0.756 mmol). The reaction mixture was added with water and sodium carbonate, followed by extracting with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure to obtain 4-[3-(tert-butoxycarbonylamino)propoxy]-7-{1-(tert-butoxycarbonyl)-5-[4-(2-hydroxyethyl)piperazin-1-ylmethyl]indol-2-yl}isoindolinone (86.5 mg, yield 69%).
