(4-bromo-2-methylbutan-2-yl)oxy-triethylsilane

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: In a similar manner to Step 1 of Example 429, 4-chloro-5-hydroxy-7-iodoisoindolinone (70.8 mg, 0.229 mmol) was dissolved in DMF (2.1 mL), and the solution was treated with potassium carbonate (94.8 mg, 0.686 mmol), tetrabutylammonium iodide (8.5 mg, 0.023 mmol) and (4-bromo-2-methyl-2-butoxy)triethylsilane (193 mg, 0.686 mmol), followed by purification by flash column chromatography (chloroform/methanol=99/1) to obtain 4-chloro-5-[3-methyl-3-(triethylsiloxy)butoxy]-7-iodoisoindolinone (40.7 mg, yield 35%). followed by purification by flash column chromatography (chloroform/methanol=99/1)
