Versuchsvorschrift

((2R,4S)-1-[(4-Methylphenyl)sulfonyl]-4-{[(4-methylphenyl)sulfonyl]oxy}pyrrolidinyl)methyl 4-methylbenzenesulfonate (1.5 g, 2.6 mmol), prepared as described in (J. Med. Chem. (1990) 33, 1344) and 3-(aminomethyl)pyridine (1.0 g, 9.3 mmol) in 20 mL of toluene were heated under reflux for 16 hours. The mixture was cooled, filtered, and the filter cake was washed with 20 mL of toluene. The filtrate was concentrated under reduced pressure and the residue was purified by chromatography (silica gel; hexanes:EtOAc, 9:1 to 1:1) to provide the title compound (410 mg, 46%). 1H NMR (DMSO-d6, 300 MHz) δ 0.86 (d, J=8.5 Hz, 1H), 1.62 (d, J=9.7 Hz, 1H), 2.42 (s, 3H), 2.44 (m, 1H), 2.66 (dd, J=2.4, 9.5 Hz, 1H), 2.99 (dd, J=2.0, 9.5 Hz, 1H), 3.39-3.48 (m, 2H), 3.62-3.41 (d, J=9.5 Hz, 1H), 4.23 (br s, 1H), 4.35 (t, J=5.1 Hz, 1H), 7.31 (m, 1H), 7.43-7.46 (m, 2H), 7.62 (m, 1H), 7.71-7.74 (m, 2H), 8.31-8.43 (m, 2H).
