The invention discloses an industrial production method for bazedoxifene acetate. The production method comprises the following steps: taking p-hydroxy benzaldehyde as a starting material, substituting with chloracetyl-hexamethyleneimine, reducing with borohydride and chlorinating with a chlorinating agent to obtain a compound 4; reacting the compound 4 with 5-(benzyloxy)-2-(4-(benzyloxy)phenyl)-3-methyl-1H-indole to obtain a compound 5; and carrying out debenzylation to obtain a compound 6, and salifying with acetic acid to obtain a target compound which is the bazedoxifene acetate. The defective workmanship of preparation in the prior art is solved, the used reagent is low in cost and easy to obtain, environmental pollution is small, safety is high, an operation process is simple, and thus, the bazedoxifene acetate is suitable for being produced industrially.
