1-[2-(2-Hydroxyethoxy)ethyl]piperazine → 4-Chloro-7-{1-(tert-butoxycarbonyl)-5-[4-(2-(2-hydroxyethoxy)ethyl)piperazin-1-ylmethyl]indol-2-yl}isoindolinone

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 1-[2-(2-hydroxyethoxy)ethyl]piperazine (35 mg, 0.20 mmol) and sodium triacetoxyborohydride (32 mg, 0.15 mmol) to obtain 4-chloro-7-{1-(tert-butoxycarbonyl)-5-[4-(2-(2-hydroxyethoxy)ethyl)piperazin-1-ylmethyl]indol-2-yl}isoindolinone.
