실험 절차

To a suspension of 2,4,6-trimethylbenzoic acid (4.6 g, 28 mmol) in 70% HNO3 (85 mL) conc. H2SO4 (5 mL). was added dropwise at RT. The brown reaction mixture was stirred for 1 h, poured into ice-water (500 mL). The product was extracted into ethyl acetate, the extract was washed with water, dried over MgSO4 and concentrated to give 3-nitro-2,4,6-trimethylbenzoic acid as a yellow solid (6.7 g, 94%).
