The invention discloses a method for synthesizing p-chloroo-toluidine, which comprises the following steps: synthesizing o-toluidine and a protective agent in an organic solvent to obtain an amino-protected intermediate. The amino protected intermediate is added into hydrochloric acid, an oxidant is added for chlorination reaction, and a chlorination product is obtained. The chlorinated product is removed and the amino protecting group is removed to give p-chloroo-toluidine. The method for synthesizing p-chloroo-toluidine provided by the invention is high in yield, simple to operate, less in three wastes, high in product content and good in quality, and can be suitable for industrial mass production.
