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).
该发明涉及使用碱性化合物对具有通式(VII)的光学活性[2-(2-
噻吩基)乙基
氨基](2-卤苯基)乙酰胺进行外消旋化过程。由此得到的通式(VII)的外消旋化合物可以再循环用于合成通式(VI)的具有治疗用途的化合物。
