实验步骤: [(cis) and (trans)]-3-(4-Methoxycyclohexyl)-propylamine: A solution of 1.18 g (7.1 mmol) 3-(4-methoxyphenyl)propylamine in 50 mL of dioxane was hydrogenated at 138 bar and at 160° C. for 16 h in the presence of 0.5 g of 5% Ru/Al2O3. The catalyst was removed by filtration and the filtrate was concentrated to dryness. Preparative HPLC of the crude product by elution with 10% (10% concd NH4OH in MeOH) --CH2Cl2 furnished 723.5 mg (59%) of the cis/trans mixture of cyclohexylpropylamine (c/t=~3:1 by 1H NMR): 1H NMR (CDCl3, cis-isomer only) δ 3.37 (br s, 1H), 3.27 (s, 3H), 2.64 (t, J=7.0 Hz, 2H), 2.10-0.87 (M, 15H); FDMS 172 (M+1). The catalyst was removed by filtration the filtrate was concentrated to dryness Preparative HPLC of the crude product by elution with 10% (10% concd NH4OH in MeOH) CH2Cl2 furnished
