Versuchsvorschrift

To a solution of 4-iodo-3-nitrophenol (5.00 g, 18.9 mmol) in acetone (50 ml) were added potassium carbonate (3.39 g, 24.6 mmol) and benzyl bromide (2.92 ml, 24.6 mmol), and the mixture was stirred at 50° C. for 6 hr. Water was added to the reaction mixture and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous sodium sulfate. After filtration, the solvent was evaporated under reduced pressure to give 4-benzyloxy-1-iodo-2-nitrobenzene. The obtained crude product (6.20 g) was used for Step 2 without further purification.
