A novel and highly efficient synthetic approach has been developed for the synthesis of deuterium-labeled olopatadine-d6 using inexpensive and commercially available dimethyl sulfate-d6 at the stage of alkylation of primary amine intermediate. The proposed synthetic path makes it possible to avoid the use of expensive labeled reagents such as dimethyl amine-d6 used as labeled precursor in the traditional
已经开发出一种新颖且高效的合成方法,用于在伯胺中间体的烷基化阶段使用廉价且可商购的硫酸二甲酯-d 6合成氘标记的olopatadine- d 6。所提出的合成途径可以避免在传统的合成途径中使用昂贵的标记试剂,例如用作标记前体的二甲基胺-d 6。通过1 H NMR和质谱数据证实了所获得的奥拉帕汀-d 6的结构。
