실험 절차

4-Methoxy-benzo[1,3]dioxole (2.03 g, 13.34 mmole) was dissolved in acetic anhydride (20 mL) and cooled in an ice bath while stirring. Nitric acid (1.5 mL) was added dropwise with an addition funnel over 30 minutes. The ice bath was removed and the mixture was stirred overnight allowing the reaction to heat up to room temperature. The mixture was poured into ice water and the product crashed out and was filtered and washed with water. The precipitate was dried under vacuum in a dessicator yielding (1.21 g, 46% yield) of 4-methoxy-6-nitro-benzo[1,3]dioxole. NMR-DMSO-d6: 7.63 (s, 1H), 7.52 (s, 1H), 6.25 (s, 2H), 3.95 (s, 3H)
