Reaction Steps

In a similar manner to Step 2 of Example 6, 4-(2-pyridinesulfonyloxy)-5-methoxy-7-[1-(tert-butoxycarbonyl)-5-formylindol-2-yl]isoindolinone (0.455 g, 0.807 mmol) was dissolved in acetonitrile (16.0 mL), and the solution was treated with dimethylamine hydrochloride (1.31 g, 16.1 mmol), triethylamine (2.20 mL, 16.1 mmol), acetic acid (0.924 mL, 16.1 mmol) and sodium triacetoxyborohydride (0.513 g, 2.42 mmol), followed by purification of the residue by flash column chromatography (chloroform/methanol=80/20) to obtain 4-(2-pyridinesulfonyloxy)-5-methoxy-7-[1-(tert-butoxycarbonyl)-5-(dimethylaminomethyl)indol-2-yl]isoindolinone (0.192 g, 40%).
