Reaction Steps

In a similar manner to Step 2 of Example 6, 4-methanesulfonyloxy-5-methoxy-7-[1-(tert-butoxycarbonyl)-4-formylindol-2-yl]isoindolinone (0.226 g, 0.452 mmol) was dissolved in acetonitrile (15.0 mL) and the solution was treated with diethylamine (0.935 mL, 9.03 mmol), acetic acid (0.517 mL, 9.03 mmol) and sodium triacetoxyborohydride (0.479 g, 2.26 mmol), followed by purification of the residue by flash column chromatography (chloroform/methanol=3/1) to obtain 4-methanesulfonyloxy-5-methoxy-7-[1-(tert-butoxycarbonyl)-4-(diethylaminomethyl)indol-2-yl]isoindolinone (0.144 g, 57%).
