504 g (3 mol) of 2-amino-4-nitro-1-methoxybenzene are introduced into 860 ml of acetic acid and 600 ml of water (or the combined main filtrate and first wash filtrate of a previous batch) and the mixture is heated to 80° C. 358 g (3.2 mol) of acetic anhydride are added dropwise in the course of 10 minutes. The mixture is subsequently stirred at 80° C. for 4 hours, and then cooled to room temperature, while stirring, by removing the heating bath and finally to 15° C. The pale yellow needles which have precipitated are filtered off with suction, washed with 300 ml of 60% strength acetic acid and 1500 ml of water in several portions and dried.
