A subject of the invention is a selective process for the preparation of derivatives of benzothiazole-4,7-diones and benzoxazole-4,7-diones monosubstituted in position 5 or in position 6 by an amino group itself optionally substituted. Said derivatives are inhibitors of the Cdc25 phosphatases and can be used for preparing medicaments intended to treat cancer. The invention also offers synthesis intermediates which are useful in implementing the process of the invention. The invention also relates in particular to the following derivatives of benzothiazole-4,7-diones: 2-(2-chloro-6-fluorophenyl)-5-[2-(dimethylamino)ethyl]amino}-1,3-benzothiazole-4,7-dione; 2-(2-chloro-6-fluorophenyl)-5-[(2-pyrrolidin-1-ylethyl)amino]-1,3-benzothiazole-4,7-dione.
本发明的一个主题是一种选择性过程,用于制备在5位或6位位置由氨基团单取代的苯并噻唑-4,7-二酮和苯并噁唑-4,7-二酮衍生物。所述衍生物是Cdc25磷酸酯酶的抑制剂,可用于制备用于治疗癌症的药物。该发明还提供了在实施该发明过程中有用的合成中间体。该发明还特别涉及苯并噻唑-4,7-二酮的以下衍生物:2-(2-氯-6-氟苯基)-5-[2-(二甲基氨基)乙基]氨基}-1,3-苯并噻唑-4,7-二酮;2-(2-氯-6-氟苯基)-5-[(2-吡咯啉-1-基乙基)氨基]-1,3-苯并噻唑-4,7-二酮。
