The invention relates to a synthesis method of t-butyloxycarboryl-3-(hydroxymethyl)-[1,2,3]triazole[1,5-a]piperidine-6-amide. The technical problem that a suitable industrial synthesis method does not exist at present is mainly solved. The synthesis method is divided into the following seven steps of firstly making (2-chloro-5-nitropyridine) and t-butyl ethyl malonate react in a solvent tetrahydrofuran under the action of NaH to obtain a compound 2; obtaining a compound 3 from the compound 2 under the action of trifluoroacetic acid; afterwards, subjecting the compound 3 to a hydrogenation reaction under the catalysis of palladium carbon to obtain a compound 4; carrying out t-butyloxycarboryl protection on the compound 4 to obtain a compound 5; making the compound 5 act with p-ABSA (p-Acetamidobenzenesulfonyl Azide) under the action of DBU (1,8-Diazabicyclo[5,4,0]undec-7-ene) to obtain a compound 6; reducing the compound 6 in the tetrahydrofuran by lithium aluminium tetrahydride to obtain a compound 7; subjecting the compound 7 to catalytic hydrogenation under the catalysis of wet palladium carbon to obtain a final compound 8.
