The invention relates to a preparation method of stable isotope labeled clenproperol, which comprises the following steps: by taking 4-amino-3,5-dichloroacetophenone (II) as a raw material, carrying out bromination reaction to prepare a compound (III), then carrying out improved Gabriel synthesis reaction, namely amination reaction with sodium diformamide to obtain a compound (IV), then carrying out hydrolysis and reduction to obtain a compound (VI), and carrying out reductive amination reaction to generate a target compound (I). The preparation method disclosed by the invention is reasonable in process design, low in raw material price, controllable in experimental process and simple and convenient to operate, various required labeled compounds such as D-labeled, 13C-labeled or D/13C double-labeled compounds can be conveniently synthesized, and the prepared target product is high in purity, can be used as an internal standard substance in the field of food safety detection, and has important practical application value.
