実験手順

In a similar manner to Step 2 of Example 6, 4-chloro-5-[3-(tert-butyldimethylsiloxy)propoxy]-7-[1-(tert-butoxycarbonyl)-5-formylindol-2-yl]isoindolinone (71.8 mg, 0.120 mmol) was dissolved in acetonitrile (2.5 mL), and the solution was treated with pyrrolidine (0.100 mL, 1.198 mmol), acetic acid (0.069 mL, 1.198 mmol) and sodium triacetoxyborohydride (76.3 mg, 0.360 mmol), followed by purification by flash column chromatography (chloroform/methanol=19/1, 4/1) to obtain 4-chloro-5-[3-(tert-butyldimethylsiloxy)propoxy]-7-[1-(tert-butoxycarbonyl)-5-(pyrrolidin-1-ylmethyl)indol-2-yl]isoindolinone (51.4 mg, yield 66%).
