The invention discloses a preparation method of an omeprazole metabolite, and belongs to the field of pharmaceutical synthesis. A reaction route is reasonable in design; the operability is high. The preparation method comprises the following steps of reacting to synthesize a target compound with eight steps of firstly enabling 5,6-methyl dimethylnicotinate to be subjected to oxidation through nitrogen, nitrifying, carrying out nitro-substitution, rearranging, chloridizing, butting with 2-mercapto-5-methoxybenzimidazole, carrying out sulfur oxidation, and carrying out hydrolysis, and the like.The whole route of the preparation method is reasonable in design; the post treatment is simple; raw materials are cheap and are easily obtained, and a prepared and obtained target product has the purity which can be up to 99.7 percent or above, can be used for pharmacokinetic study, is used for providing a test sample for the study of a metabolic mechanism of omeprazole, and has important application value.
