A solution of 3-methoxyphenol (10 g, 80.55 mmol) in propionic acid (80 mL) was treated at −5° C. with a solution of NaNO2 (5.61 g, 81.30 mmol) in water (13 mL). After stirring for 1 h at −5° C., nitric acid (6.7 mL, 161.10 mmol) was added. The slurry was stirred for 1 h at −5° C., and then at room temperature for 16 h. Water (80 mL) was then added in a dropwise fashion at room temperature. The resultant solid was filtered, washed with 50% aqueous propionic acid, and dried to give 7.47 g (55%) of 5-methoxy-2-nitro-phenol.
