    • At room temperature 10 mL acetic anhydride was dropped in 10 mL 98% nitric acid keeping the temperature below 30 °C. Then compound 2 (1.12 g, 2.96 mmol) was added into this mixture slowly. The reaction temperature was elevated to 50 °C. After 2 h the mixture was poured into ice-water. Compound 3 1.1 g (68.3, was obtained as white power and purified by recrystallization in acetone. After dissolving compound 3 (1.12 g, 2.5 mmol) in the mixture of 98% nitric acid (6 mL) and 25% Oleum(3 mL) at 0 °C, the reaction temperature was elevated to 80 °C and kept for 2 h .Then the reaction mixture was filtered and compound 4 0.6 g (52.6, was obtained, which was recrystallized from 67% nitric acid. The data of compound 3: FTIR IR (KBr, ν, cm-1, 3031, 1697, 1655, 1598, 1307; 1H NMR (400 MHz, CD3COCD3, δ 2.13-2.31 (m, 12H, 4CH3, 5.326 (s, 2H, CH2, 6.049-6.090 (d, 2H on C4 and C6, 6.808-6.739 t, 2H on C1
