The invention provides a preparation method of a salbutamol sulfate intermediate. Salbutamol is a beta receptor stimulant; a current preparation technology of the salbutamol mainly takes an original research technology as a main part; the original research technology takes p-hydroxyacetophenone as a starting material and the salbutamol is prepared through chloromethylation, esterification, bromination, amination, hydrolysis and reduction. An existing synthesis method of the salbutamol sulfate intermediate is used for synthesizing through a plurality of steps and is complicated to operate; theloss of products in a preparation process is great and the technological time is relatively long. The preparation method of the salbutamol sulfate intermediate, provided by the invention, comprises the following steps: reducing carbonyl of a compound I under the action of a reducing agent to obtain a compound II; then adding a debenzylation reagent and carrying out debenzylation reaction to obtainthe salbutamol sulfate intermediate III. According to the preparation method, the salbutamol sulfate intermediate III is prepared from the compound I by adopting a 'one-pot method'; operation steps are reduced, the reaction time is shortened and the reaction yield is improved.

Three known and one unknown impurities in salbutamol sulphate bulk drug at level 0.1% (ranging from 0.05-0.1%) were detected by gradient reverse phase high performance liquid chromatography. These impurities were preliminarily identified by the mass number of the impurities. Different experiments were conducted and finally synthesized and characterized the known and unknown imputities.
