Purpose To prepare 1-metyh1-3-ethy1-3(3-hydroxyhenyl)-hexahydro-1 H-azepin hy-drochloride (I) from m-methoxyacetophenone. Methods 1-methy1-3-(3-hydrox yphenyl)-hex-ahydro-1 H-azepin hydrochloride (I) was synthesized by eight steeps with m-methoxyacetophenone as start-ing material. The eight steps were willgerodt rearrangement, formation of acyl chloride, acylride and salt for-mation. Results 1-methy1-3-ethy1-3(3-hydroxypheny1)-hexahydro-1 H-azepin Hydrochlorde (I) was prepared in eight steps from cheap material and reagent on normal condition. Conclusions This method is applicable to industrial production.
