Participants

Reaction Steps

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). The solution was treated with 2-(2-aminoethoxy)ethanol (0.010 mL, 0.10 mmol) and sodium triacetoxyborohydride (48 mg, 0.23 mmol) to obtain 4-chloro-7-{1-(tert-butoxycarbonyl)-5-[2-(2-hydroxyethoxy)ethylaminomethyl]indol-2-yl}isoindolinone.
