The invention discloses a preparation method for a rosuvastatin calcium intermediate impurity. The preparation method comprises: by taking formaldehyde and [4-(4-fluorophenyl)-6-isopropyl-2-(N-methyl-methanesulfonamino)-5-pyrimidyl] triphenylphosphonium bromide as raw materials, carrying out Witting reaction; and carrying out treatment and recrystallization to obtain a target compound. The preparation method has the characteristics of being original, simple to operate, high in product purity, high in yield and the like. The preparation method disclosed by the invention has the benefit that the preparation method provides certain help for registration and application, production and center control of rosuvastatin calcium as well as improvement of quality of rosuvastatin calcium. The formula is shown in the description.
