摘要:The present invention provides novel processes for purifying anastrozole, devoid of using liquid chromatography. The purification processes are via the isolated anastrozole salt forms, either by crystallization or by selective acidic extractions, and optionally in both cases, converting the purified anastrozole salt to anastrozole base. Also provided is an improved process for the synthesis of anastrozole, which is obtained by alkylating the isolated and purified starting material 3,5-bis(2-cyanoprop-2-yl)benzylbromide, the process being devoid of using toxic, hazardous and environmental unfriendly solvents and reagents.
