実験手順

2-Methyl-1,4-bis(methyloxy)benzene (6.12 g, 40 mmol) was dissolved in acetic acid (20 mL) and heated at 40° C. A solution of nitric acid (4.32 g) in acetic acid (10 mL) was added to above solution drop wise over 5 minutes. The reaction mixture was stirred at 40° C. for 30 min (yellow precipitates formed), then room temperature for 30 min and then diluted with water (300 mL). The precipitate was collected by filtration, washed with water, and dried in the air for 16 h to afford the title compound (7.56 g, 96%) as a yellow solid. MS (ES) m/e 198 [M+H]+.
