Versuchsvorschrift

Chloroform (5 mL) was added to a 200 mL round-bottomed flask containing 1,1-dimethylethyl 4-(1-{[trans-2-phenylcyclopropyl]amino}ethyl)-1-piperidinecarboxylate (67 mg, 0.194 mmol) to give a suspension. HCl/1,4-Dioxane (1.5 mL, 6.00 mmol) was added and the mixture stirred 18 hours at room temperature. The Upon completion, the solvents were removed, MeOH (1 mL) added and the mixture purified via reverse phase column chromatography on Gilson ((C18 column: 0.1% Formic acid H2O/CH3CN, 95-5%) affording the title compound as a white solid LC-MS (ES) m/z=245 (M+H)+, 1H NMR (400 MHz, MeOD-d4) δ ppm 1H NMR (400 MHz, MeOD) d 7.93 (s, 1H), 7.31-7.39 (m, 2H), 7.17-7.30 (m, 3H), 3.46-3.59 (m, 3H), 2.95-3.14 (m, 3H), 2.50-2.63 (m, 1H), 2.17-2.28 (m, 1H), 1.94-2.05 (m, 3H), 1.59-1.76 (m, 3H), 1.48 (t, J=7.71 Hz, 1H), 1.39 (d, J=6.82 Hz, 3H).
