Versuchsvorschrift

2-Nitro-4,6-dichloroanisole was prepared by the same procedure as described for Step 2 of Preparation 2a except using 2,4-dichloro-6-nitrophenol (52 g), methyl iodide (71 g), and potassium carbonate (41.4 g). Workup gave crude 2-nitro-4,6-dichloroanisole (50 g, 90%) which was used in the next step without purification.
