실험 절차
A stirred mixture of sulphuric acid (200 ml) and nitric acid (200 ml) was treated with 5,6,7,8-tetrahydroquinoline N-oxide (47 g, 315 mmol), heated at 60°-80° for 3h, cooled to room temperature, poured onto ice (1 Kg), diluted with water (1 1), and extracted with dichloromethane (3×500 ml). The extracts were dried (MgSO4) and evaporated in vacuo to give the product (48 g) as an oil.
