The invention discloses a terbutaline sulfate intermediate and a preparation method thereof as well as a method for preparing terbutaline sulfate by using the same, and belongs to the technical field of pharmaceutical chemistry. The invention provides a novel method for preparing terbutaline sulfate which is mild in reaction condition, high in yield and environmentally friendly, and firstly provides a terbutaline sulfate intermediate shown as a formula I; then, a catalyst is used as 10% Pd/C, an alcohol aqueous solution is used as a solvent, and hydrogenation is reduced to obtain the terbutaline II sulfate. The free base hydrochloride or hydrobromide of the formula I is converted into the formula I before hydrogenation reduction, then the terbutaline sulfate is directly obtained after hydrogenation reduction, and the advantages of mild reaction conditions, high product yield, high purity, low production cost and the like are avoided.
