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).
本发明涉及使用碱性化合物进行光学活性[2-(2-
噻吩基)乙基
氨](2-卤代苯基)乙
酰胺类化合物(通式(VII))的外消旋化过程。因此,通式(VII)的产生的外消旋化化合物可以回收再利用于通式(VI)的治疗用化合物的合成。
