This compound was prepared in a manner similar to that described for 1,2,3,4-tetrahydro-2,2-dimethyl-7-nitroquinoline (Scheme III) from for 2,2-diethyl-1,2,3,4-tetrahydroquinoline (0.955 g, 5.04 mmol) and fuming HNO3 (0.32 g, 5.0 mmol) in concentrated sulfuric acid (10 mL) to afford 0.811 g (69%) of 2,2-diethyl-1,2,3,4-tetrahydro-7-nitroquinoline after chromatography (hexanes:EtOAc, 24:1). Data for 2,2-diethyl-1,2,3,4-tetrahydro-7-nitroquinoline: Rf 0.43 (24:1 hexanes:ethyl acetate); 1H NMR (400 MHz, CDCl3) 7.38 (dd, J=8.3, 2.3, 1H), 7.29 (d, J=2.3, 1H), 7.04 (d, J=8.3, 1H), 4.00 (broad s, 1H), 2.78 (t, J=6.7, 2H), 1.71 (t, J=6.7, 2H), 1.38-1.58 (m, 4H), 0.88 (t, J=7.4, 6H).
