Procedure

50.0 g of 3-methoxyacetophenone was added slowly, drop-by-drop, to 250 ml of 70% nitric acid at room temperature. The mixture was allowed to stand for 17 hours, warmed and held at 40° C. for 1 hour, cooled and diluted to three times its volume with water. The resulting mixture was extracted with ethyl acetate. The extract was washed with water, then with saturated sodium chloride solution, dried (Na2SO4) and the solvent was evaporated. The residue was dissolved in ethyl acetate, hexane was added and the mixture was set in dry ice. The solid that formed was collected and dried under reduced pressure to give 3-methoxy-2-nitroacetophenone (4A), as a cream-colored solid, m.p.: 125°-127°C.
