The invention provides a method for preparing a highly pure delamanid intermediate. The intermediate is 4-[4-(trifluoromethoxy)phenoxyl]piperidine. Hydrogen chloride is dissolved in ethyl acetate in a Boc group removal step, and the dissolvability difference between the above product and impurities in ethylene acetate is used to carry out purification, so a column chromatography purifying method using tedious operation is avoided, the final product with high yield and high purity is also obtained, the production cost is reduced, and the method is suitable for industrial large-scale production.
