In a similar manner to Step 1 of Example 56, 4-chloro-7-[1-(tert-butoxycarbonyl)-5-formylindol-2-yl]isoindolinone (20.0 mg, 0.0487 mmol) was dissolved in dichloromethane (0.5 mL), and the solution was treated with 1-amino-1-cyclopentanemethanol (23 mg, 0.20 mmol) and sodium triacetoxyborohydride (48 mg, 0.23 mmol) to obtain 4-chloro-7-{1-(tert-butoxycarbonyl)-5-[(1-hydroxymethylcyclopentyl)aminomethyl]indol-2-yl}isoindolinone was obtained.
