Versuchsvorschrift

56.5 g of 5-acetamino-1,3-benzodioxole in 250 ml of glacial acetic acid were nitrated as described above with a solution of 30 ml of nitric acid in 100 ml of glacial acetic acid in a 500 ml sulfonation flask equipped with stirrer, thermometer and dropping funnel. The crystals, removed by filtration under suction, were ashed thoroughly with water and dried overnight at about 60° C. in vacuo. There were obtained 68.3 g (96.6% of theory) of 5-acetamino-6-nitro-1,3-benzodioxole of melting point 211°-213° C.
