実験手順
In a similar manner to Step 2 of Example 6, 4-methanesulfonyloxy-5-methoxy-7-[1-(tert-butoxycarbonyl)-5-formylindol-2-yl]isoindolinone (100 mg, 0.200 mmol) was dissolved in acetonitrile (5.8 mL), and the solution was treated with 3-(2-aminoethyl)pyridine (0.235 mL, 2.00 mmol), acetic acid (0.229 mL, 4.00 mmol) and sodium triacetoxyborohydride (127 mg, 0.599 mmol), followed by purification by preparative thin-layer chromatography (chloroform/methanol=4/1) to obtain 4-methanesulfonyloxy-5-methoxy-7-{1-(tert-butoxycarbonyl)-5-[(2-(pyridin-3-yl)ethyl)aminomethyl]indol-2-yl}isoindolinone (80.5 mg, yield 66%).
