PROCEDURE

实验过程

0.200 g (1.00 mmol) of commercially available 2-chloro-1,3-dinitrobenzene was dissolved in a warm solution of 15 ml methanol and 0.223 g (4.13 mmol) of NaOMe. The reaction was stirred overnight with continued warming. The residue was dissolved in water after evaporation of the solvent. The aqueous solution was extracted with dichloromethane, dried and evaporated under reduced pressure to give 0.187 g of 2,6-dinitroanisole (95%) as yellow flakes. 1H NMR (CDCl3) δ 8.06 (d, J=8.2 Hz, 2H, Ar—H), 7.38 (t, J=8.2 Hz, 1H, Ar—H), 4.09 (s, 3H, O—CH3). 13C NMR (CDCl3) δ 148.0, 129.4, 124.2, 65.1.
