The invention provides a method for preparing edoxaban by using 2, 2, 2-trichloro-1-(4, 5, 6, 7-tetrahydro-5-methylthiazolo[5, 4-c]pyridinium-1-yl) ethanone chloride. The preparation method comprisesthe following steps: preparing 2, 2, 2-trichloro-1-(4, 5, 6, 7-tetrahydro-5-methylthiazolo[5, 4-c]pyridinium-1-yl) ethanone chloride, namely 109C5-11; the invention discloses a preparation method of N1[(1S, 2R, 4S)-2-amino-4-[(dimethylamino) carbonyl]cyclohexyl]-N2(5-chloro-2-pyridyl) oxalamide dimesylate, namely 109T2-31. The 109C5-11 is used as an acylation reagent to prepare the edoxaban with 109T2-31. The preparation method comprises the following steps: preparing the edoxaban by using the 109C5-11 as the acylation reagent; the novel method overcomes the defect that expensive condensing agents EDCI.HCl and activating agents HOBt need to be used in the prior art. The new method provided by the invention is beneficial to more economically and more efficiently realizing industrial scale production of the Edoxaban p-toluenesulfonate hydrate.
