The invention discloses a preparation method of a compound 2-[4-((3S)-3-piperidyl)phenyl]-2H-indazole-7-formamide tosilate monohydrate. The method includes: carrying out Ulman reaction on 1H-indazole-7-methyl formate and (S)-3-(4-halogenophenyl)piperidine-1-tert-butyl formate to prepare 2-[4-((3S)-3-piperidyl)phenyl]-2H-indazole-7-methyl formate, then under the conditions of ammonia gas and p-toluenesulfonic acid, preparing 2-[4-((3S)-3-piperidyl)phenyl]-2H-indazole-7-formamide tosilate monohydrate. The invention aims to avoid the disadvantages of existing methods, shortens the preparation route, and provides the preparation method of the 2-[4-((3S)-3-piperidyl)phenyl]-2H-indazole-7-formamide tosilate monohydrate with high chiral purity, and the method has the characteristics of mild reaction and easy operation.
