    摘要: The invention relates to the racemisation process of the optically active [2-(2-thienyl)ethylamino](2-halogenophenyl)acetamides of general formula (VII) by using basic compounds. The resulting racemic compounds of general formula (VII) can thus be recycled into synthesis of the therapeutically useful compounds of general formula (VI).

    摘要: The invention relates to a novel process for preparation of dronedarone (I) and pharmaceutically acceptable salts thereof where the compound of formula (II) or salt thereof is reacted with a compound of formula L-(CH2)3—CH3 (III), where L is a leaving group, and isolating the obtained product and, if desired, converting it into a pharmaceutically acceptable salt thereof. The invention also relates to some novel intermediary compounds and the preparation thereof.
