The Improved Synthesis of Flurbiprofer |
LIU Yin-long (Hunan Dongting Pharmaceutical Company Limited; Changde 415000; China) |
Abstract:Flurbiprofer was synthesized from 4-acetyl-2-fluorobiphenyl by ring oxidize、esterification、condensation、hydrolyzation and decarboxylation reaction.Inflammable ether was not used and vacuum distillation was omitted.This method is simple、reasonable reliable, and it could be used in the industry on a large scale. |
Key words:flurbiprofer; synthesis; 4-acetyl-2-fluorobiphenyl |
