Versuchsvorschrift

4-Chloro-5-methyl-2-nitroanisole was prepared by the same procedure as described for Step 2 of Preparation 2a except using 4-chloro-5-methyl-2-nitrophenol (50 g), methyl iodide (75.8 g), and potassium carbonate (44 g). Workup gave crude 4-chloro-5-methyl-2-nitroanisole (52.3 g, 97%) which was used in the next step without purification. 1H NMR (300 MHz, CDCl3) δ7.85 (s, 1 H), 6.95 (s, 1 H), 3.94 (s, 3 H), 2.45 (s, 3 H).
