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.
