1,2-Ethanediamine, N1,N1,N2-trimethyl- → 4-chloro-7-(1-(tert-butoxycarbonyl)-5-[N-(2-(dimethylamino)ethyl)-N-methylaminomethyl]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 N,N,N′-trimethylethylenediamine (32 mg, 0.20 mmol) and sodium triacetoxyborohydride (32 mg, 0.15 mmol) to obtain 4-chloro-7-(1-(tert-butoxycarbonyl)-5-[N-(2-(dimethylamino)ethyl)-N-methylaminomethyl]indol-2-yl)isoindolinone.
