PROCEDURE

实验过程

In a similar manner to Step 2 of Example 6, 4-methanesulfonyloxy-5-methoxy-7-[1-(tert-butoxycarbonyl)-4-formylindol-2-yl]isoindolinone (0.299 g, 0.597 mmol) was dissolved in acetonitrile (15.0 mL), and the solution was treated with pyrrolidine (0.997 mL, 11.9 mmol), acetic acid (0.684 mL, 11.9 mmol) and sodium triacetoxyborohydride (0.633 g, 2.99 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-(pyrrolidin-1-ylmethyl)indol-2-yl]isoindolinone (0.117 g, yield 35%).
