实验步骤: 1,2,3,4-Tetrahydro-4-methylquinoline (55 mg, 0.337 mmol) was dissolved in sulfuric acid (0.5 mL) and the temperature was lowered to 0° C. To this solution 90% fuming nitric acid (15 mL, 0.337 mmol) was added slowly and the mixture stirred at 0° C. for 1 h, then warmed to rt. The reaction mixture was poured onto 1 g of ice and extracted with dichloromethylane (2×5 mL). The organic phase was washed with sat. NaHCO3 (1×3 mL) and concentrated in vacuo to a reddish residue that was subjected to chromatography (silica gel, hexanes/ethyl acetate, 8:2) which afforded 36 mg (52%) of 7-nitro-1,2,3,4-tetrahydro-4-methylquinoline. Data for 7-nitro-1,2,3,4-tetrahydro-4-methylquinoline: 1H NMR (400 MHz, CDCl3) 7.41 (dd, J=8.3, 2.2, 1H), 7.27 (d, J=2.3, 1H), 7.11 (d, J=8.3, 1H), 4.21 (s, 1H), 3.35 (m, 2H), 2.95 (m, 1H), 1.96 (m, 1H), 1.72 (m, 1H), 1.3 (d, J=7.0, 3H). was lowered to 0° C was added slowly warmed to rt extracted with dichloromethylane (2×5 mL) The organic phase was washed with sat.
