Versuchsvorschrift

In a similar manner to Step 2 of Example 6, 4-chloro-7-[1-(tert-butoxycarbonyl)-5-formylindol-2-yl]isoindolinone (40.0 mg, 0.0974 mmol) was dissolved in acetonitrile (2 mL), and the solution was treated with 2-aminoethanol (0.024 mL, 0.39 mmol), acetic acid (0.112 mL, 1.96 mmol) and sodium triacetoxyborohydride (103 mg, 0.486 mmol), followed by purification by preparative thin-layer chromatography (hexane/ethyl acetate=1/2) to obtain 4-chloro-7-(1-(tert-butoxycarbonyl)-5-[(2-hydroxyethyl)aminomethyl]indol-2-yl)isoindolinone (39.4 mg, yield 871).
