The invention discloses a method for preparing ceritinib, belonging to the field of chemical pharmacy. The method comprises the following steps: by taking 3-bromine-4-methylphenol as an initial raw material, performing phenolic hydroxyl isopropylation, nitration, coupling and reduction reaction, obtaining a midbody 1, by further taking o-nitro fluorobenzene as another initial raw material, performing isosulfhydrylation, oxidation, reduction and pyrimidine, obtaining a midbody 2, performing coupling reduction on the midbody 1 and the midbody 1, obtaining ceritinib which is protected by BOC acid anhydride, and finally removing a t-butyloxycarboryl protecting group, and obtaining ceritinib. The method is simple and feasible to operate, relatively high in yield, small in pollution and applicable to industrial production.
