실험 절차

5,6,7,8-Tetrahydro-2(1H)-quinolinone (0.134 mol) was added portionwise at 5° C. to sulfuric acid (200 ml). Then HNO3 (0.235 mol) was added portionwise while the temperature was kept below 10° C. The mixture was stirred at 5° C. for 1 hour, poured out carefully into a small amount of ice water and stirred at 0° C. for 10 min. The precipitate was filtered off and dried, yielding 14.2 g (55%) of 5,6,7,8-tetrahydro-3-nitro-2(1H)-quinolinone (intermediate 8)
