Procedure

8.3 g (35 mmol) of 1-ethyl-6-nitro-2,3(1H,4H)-quinoxalinedione were dissolved in 300 ml of dimethylformamide and, after addition of 2 g of palladium/carbon (10%), were hydrogenated. The mixture was then filtered and the filtrate was concentrated under reduced pressure to yield 5.9 g (81%) of the product.

Workup

  1. filtrationThe mixture was then filtered
  2. concentrationthe filtrate was concentrated under reduced pressure
