Procedure
Methyl 4-aminophenylacetate (110 g, 0.667 mol) was added dropwise to acetic anhydride (600 ml), maintaining the temperature of the reaction mixture below 30° C. by external cooling. Once the addition was complete the mixture was cooled to below 10° C. and concentrated nitric acid (85 ml) was added dropwise. Once the addition of the acid was complete, the mixture was allowed to warm to room temperature and poured onto a mixture of ice and water. The precipitated solid was collected by filtration and dried to give methyl 4-acetamido-3-nitrophenylacetate (120 g) as a pale yellow solid.
