Versuchsvorschrift

In a similar manner to Step 4 of Example 140, 7-amino-4-(4-tert-butyldimethylsilyloxyphenyl)isoindolinone (179 mg, 0.505 mmol) was dissolved in acetonitrile (12.5 mL), and the solution was treated with potassium iodide (133 mg, 0.808 mmol), copper iodide (152 mg, 0.808 mmol), iodine (203 mg, 0.808 mmol) and tert-butyl nitrate (0.127 mL, 1.06 mmol), followed by purification by flash column chromatography (chloroform) to obtain 7-iodo-4-(4-tert-butyldimethylsilyloxyphenyl)isoindolinone (109 mg, yield 47%).

Aufarbeitung
