Procedure

N-(4-Ethoxy-3-ethyl-phenyl) acetamide [3.1 g, Reference Example 33(e)] was dissolved in acetic anhydride (5 mL), a solution of nitric acid in acetic acid (0.5 mL of 95% nitric acid, in 4 mL) was added and the mixture was stirred overnight at ambient temperature. The mixture was diluted with water (100 mL) and the aqueous mixture was extracted twice with ethyl acetate (100 mL). The combined extracts were evaporated and the residue was chromatographed on silica gel (heptane/ethyl acetate 9/1) to give N-(4-ethoxy-5-ethyl-2-nitrophenyl)acetamide (3.0 g) as a bright yellow solid. LC-MS (Method E): RT=3.27 minutes, 253 (M+H)+.
