Versuchsvorschrift

To a stirred solution of (S)-nicotine (0.12 g, 0.71 mmol) in AcOH (2 ml) was added 8-bromo-oct-1-ene (0.34 g, 1.8 mmol). The mixture was heated at reflux for 3 days. AcOH was evaporated and the residue was dissolved in CHCl3. The mixture was washed with saturated aqueous NaHCO3, water and brine successively and dried. Evaporation of the solvent followed by titration with ether afforded 0.19 g (77%) of (S)-3-(1-methyl-pyrrolidin-2-yl)-1-oct-7-enyl-pyridinium bromide (NONB-7e) as a brown oil. 1H NMR (300 MHz, CDCl3) δ 9.70 (1H, d, J=6.0 Hz), 9.21 (1H, s), 8.41 (1H, d, J=8.1 Hz), 8.08 (1H, dd, J=8.1, 6.0 Hz), 5.72 (1H, m), 4.86–5.10 (4H, m), 3.50 (1H, t, J=8.4 Hz), 3.22 (1H, m), 2.41 (2H, m), 2.20 (3H, s), 1.80–2.10 (6H, m), 1.61 (1H, m), 1.20–1.44 (6H, m); 13C NMR (75 MHz, CDCl3) δ 146.12, 144.00, 143.28, 142.63, 138.22, 128.05, 114.20, 66.68, 61.67, 56.48, 40.29, 35.67, 33.30, 31.88, 28.33, 28.27, 25.76, 22.98; Anal.
