实验步骤: A mixture of 5-benzoyl-2-nitrobenzaldehyde (0.0058 mol) in THF (100 ml) was hydrogenated with 10% Pd/C (1 g) as a catalyst in the presence of 4% thiophene solution (1 mL). After uptake of H2 (3 equiv), the mixture was put in an autoclave. N-cyclohexyl, N-methyl-propane-1,3-diamine (0.01 mol) and CaH2 (0.5 g) were added and the mixture was reacted under 10 atm of CO2 and 50 atm of H2 at 50° C. for 16 hours. When the reaction was complete, the mixture was purified over silica gel on a glass filter (eluent: 90:10 CH2Cl2:(CH3OH:NH3)). The product fractions were collected and the solvent was evaporated to yield the title compound as a residue. the mixture was purified over silica gel on a glass filter (eluent: 90:10 CH2Cl2:(CH3OH:NH3)) The product fractions were collected the solvent was evaporated

实验步骤: 75.0 g (0.87 mol) of pivalaldehyde are added dropwise to a solution of 76.7 g (0.87 mol) of 3-methylaminopropylamine in 200 ml of dry cyclohexane. After the addition, the solution is heated under reflux in a water separator for 3 hours. The solvent is then removed in a rotary evaporator and the residue is distilled. Boiling point: 69° C./67 mbar After the addition the solution is heated The solvent is then removed in a rotary evaporator the residue is distilled

实验步骤: To a solution of toluene and 4,4 dipropylcyclohexane 1 carboxy 1 acetic acid anhydride (1 equivalent) was added 3 methylaminopropylamine (1.05 equivalents). The reaction mixture was heated at reflux using a Dean Stark trap. Following collection of water (1 equivalent), the reaction mixture was cooled to room temperature and concentrated under reduced pressure. The residue was used without further purification. The reaction mixture was heated at reflux concentrated under reduced pressure The residue was used without further purification

实验步骤: Ethyl trifluoroacetate [383-63-1] (7.5 mL, 62.9 mmol) was slowly added to an ambient temperature solution of N1-methylpropane-1,3-diamine [6291-84-5] (6.5 mL, 62.8 mmol) in anhydrous THF (100 mL) then allowed to stir, under N2 blanket for 17 h. The reaction solution was then evaporated to provide 12.3 g of clear colorless liquid. LRMS (ESI) m/z 185.1 [(M+H)]+, calc'd for C6H11F3N2O: 184.16. The reaction solution was then evaporated
