Reaction Steps
3-Methyl-4-(methylsulfonyl)phenol (D85, 503 mg, 2.29 mmol) was dissolved in DCM (5 mL) and 70% nitric acid (0.16 mL, 3.58 mmol) was added dropwise to the reaction. The mixture was stirred o/n. A further 2 mL of 70% nitric acid was then added. The reaction was stirred for 4 h, then H2O (20 mL) was added and the 2 phases were separated. The aqueous layer was extracted with DCM and the combined organics were dried (Na2SO4) and concentrated by rotary evaporation to give a yellow solid, which was purified via flash column chromatography (silica, iso-hexane to 50% EtOAc/50% iso-hexane) to give a yellow solid. This solid was triturated with Et2O (2×) to give 5-methyl-4-(methylsulfonyl)-2-nitrophenol (D86, 103 mg, 19%) as a yellow solid.
