実験手順
13.5 g of 7-acetamino-3,4-dihydro-2H-1,5-benzodioxepine were placed in 50 ml of glacial acetic acid and nitrated at 15°-20° C. with 7 ml of nitric acid in 20 ml of glacial acetic acid by dropwise addition, the crystals passing into solution only after the addition of a quarter of the nitric acid. The product separated out, but was stirred for an additional 3 hours, then removed under suction and washed with water and methanol. 15.6 g (94.9% of theory) of 7-acetamino-8-nitro-3,4-dihydro-2H-1,5-benzodioxepine of melting point 139°-140° C. were obtained.
