Reaction Steps
To a solution of nitric acid (20.0 mL) and acetic acid (40.0 mL) under 10° C. was added 3,4,5-trimethoxybenzoic acid (10.0 g, 47.0 mmol) in portions. The mixture was stirred at room temperature for 30 minutes. The reaction mixture was then poured into ice-water. The resulting precipitate was collected by filtration and washed with water, which was then recrystallized from ethanol to afford the product 1,2,3-trimethoxy-5-nitrobenzene (6.64 g, yield 66.1%). 1H NMR (400 MHz, DMSO-d6) δ ppm 7.51 (s, 2H), 3.87 (s, 6H), 3.77 (s, 3H).
