Versuchsvorschrift
In a similar manner to Step 2 of Example 6, 4-methanesulfonyloxy-5-methoxy-7-[1-(tert-butoxycarbonyl)-5-formylindol-2-yl]isoindolinone (1.02 g, 2.66 mmol) was dissolved in acetonitrile (13.0 mL), and the solution was treated with 2-methoxyethylamine (3.47 mL, 39.9 mmol), acetic acid (2.28 mL, 13.3 mmol) and sodium triacetoxyborohydride (2.82 g, 39.9 mmol), followed by purification by flash column chromatography (chloroform/methanol=4/1) to obtain 4-methanesulfonyloxy-5-methoxy-7-[1-(tert-butoxycarbonyl)-5-(2-methoxyethylaminomethyl)indol-2-yl]isoindolinone (0.83 g, 56%).
Aufarbeitung
- customfollowed by purification by flash column chromatography (chloroform/methanol=4/1)
