Provided is a method for preparing ticarcillin disodium with less side reaction and strong controllability in mild reaction condition using fewer steps, which comprises (1) reacting 3-thiophene malonic acid with N-hydroxyl succinimide in an organic solvent and under catalysis of DCC and DMAP to obtain an intermediate 1 that is separated and purified by column chromatography, (2) dissolving the intermediate 1 in methylene dichloride and adding 6-APA and an alkali to obtain ticarcillin, and (3) reacting ticarcillin with a salt forming agent to obtain ticarcillin disodium.
