Procedure

1-Methyl-3,4-dihydro-1H-benzo[e][1,4]diazapine-2,5-dione (3.4 g, 17.9 mmol) was dissolved in concentrated sulfuric acid (30 ml) and to this was added potassium nitrate (1.95 g, 19.3 mmol) at 0° C. The mixture was stirred overnight, dumped onto ice, and the solids filtered off (3.62 g, 86%), m.p. 274-276° C.

Workup
