The invention discloses a preparation method and a detection method of 
febuxostat raw material. The preparation method comprises Cyanophenol, DMF (
Dimethyl Formamide) saturated with HCl, and 
thioacetamide are mixed and react to obtain an intermediateIII; the intermediate III, 
anhydrous ethyl 
alcohol, 2-chlorination acetoacetic ester are mixed and react to obtain an intermediate IV; the intermediate IV, hexamethylene 
tetramine and polyphosphoric acid are mixed and react to obtain an intermediate V; the intermediate V, DMF, 
anhydrous potassium carbonate and bromo-2-methylpropane are mixed and react to obtain an intermediate VI; the intermediate VI, 
anhydrous formic acid, oxammonium 
hydrochloride and 
sodium formate are mixed and react to obtain an intermediate VII; the intermediate VII, anhydrous ethyl 
alcohol and 
sodium hydroxide are mixed and react to obtain a 
febuxostat crude product; and refining and 
crystal transformation are performed to the 
febuxostat crude product to obtain the febuxostat 
raw material. Aiming at avoiding defects in the prior art, the preparation technology of the febuxostat 
raw material is optimized, and a systematic, complete and effective component identifying and content measuring method is established.
