PROCESS FOR THE PRODUCTION OF BENZOFURANS
摘要:
A process for the production of 2-alkyl-3-aroyl-5-nitrobenzofurans by acylation of 2-(2-hydroxy-5-nitrophenyl)-1-aryl-ethanones and subsequent treatment of the esters with combinations of bases and proton acids or Lewis acids. This process can be used for the production of Dronedarone. Furthermore, novel intermediates for the manufacture of Dronedarone are provided.
