Versuchsvorschrift

In a similar manner to Step 1 of Example 299, 4-chloro-5-hydroxy-7-[1-(tert-butoxycarbonyl)-5-(piperidin-1-ylmethyl)indol-2-yl]Isoindolinone (550 mg, 1.12 mmol) was dissolved in dichloromethane (22 mL), and the solution was treated with triethylamine (0.78 ml, 5.56 mmol) and trifluoromethanesulfonyl chloride (0.356 mL, 3.34 mmol), followed by purification by flash chromatography (chloroform, chloroform/methanol=99/1, 95/1) to obtain 4-chloro-5-trifluoromethanesulfonyloxy-7-[1-(tert-butoxycarbonyl)-5-(piperidin-1-ylmethyl)indol-2-yl]isoindolinone (491 mg, yield 71%).

Aufarbeitung

  1. customfollowed by purification by flash chromatography (chloroform, chloroform/methanol=99/1, 95/1)
