Reaction Steps
One mole of 4-methoxy-phenol in a mixture of 300 ml acetic anhydride and 300 ml acetic acid was refluxed for 12 hours. After cooling, 54 ml of nitric acid (1.3 equivalents, fuming nitric acid, d=1.52) was added dropwise at room temperature. The temperature rose to about 70° C. and nitrous vapors appeared. After completion of the addition the mixture was left under stirring for 2 hours to give 4-methoxy-3-nitrophenyl acetate as a precipitate. Isopropyl ether (300 ml) was added and the mixture was cooled to 0° C. The precipitated material was collected and dried, giving 190 g (yield=90%), m.p. 116° C.
