Embodiment 1-19

[0038] A preparation method of 4-carbamate-3-methoxycinnamic acid cyclic amine alkyl amides compound, comprises the steps:

[0039] The first step: using phthalimide potassium salt as the starting material, reacting with 1-substituted-4-chloroalkylpiperidine in the first solvent and the first basic condition to obtain phthalimide imidoalkylamine compounds;

[0040] The second step: adding the phthalimide alkylamine compound obtained in the first step into the second solvent, adding N 2 h 4 .H 2 0, warming up to reflux and stirring reaction (reaction progress tracked with TLC); after the reaction was finished, suction filtration while hot, a small amount of ethanol washed the filter cake, the filtrate was evaporated under reduced pressure to remove the solvent, and the residue was purified by column chromatography (eluent: two Chloromethane:methanol=15:1v / v) to obtain alkylamino primary amine compounds;

[0041] The third step: the primary amine compound obtained in the sec...

Embodiment 20

[0067] The specific process conditions are the same as those in Example 1-2, and the difference is the same as in the investigation of different substituents. The specific substituents are shown in Table 5, and the resulting 4-carbamate-3-methoxycinnamic acid cyclic amine alkyl amides compound , and its chemical structure was confirmed by 1H-NMR, 13C-NMR and ESI-MS.
