반응 단계
Patent application WO0248132 describes a method for the synthesis of dronedarone using 2-n-butyl-5-nitro-benzofuran which is reduced, under pressure, with hydrogen in the presence of platinum oxide as catalyst in order to form 2-n-butyl-5-amino-benzofuran. This benzofuran derivative is then subjected to the action of methanesulfonyl chloride, which gives 2-n-butyl-5-methanesulfonamido-benzofuran which is treated with 4-[3-(di-n-butylamino)-propoxy]-benzoyl chloride to give dronedarone.
