A practical large-scale synthesis was developed for the preparation of N,N′-bis(4,6-disubstituted 1,3,5-triazin-2-yl)-4-aminophenethylamine derivatives exemplified by compound 2. This route is a six-step procedure starting from commercially available cyanuric chloride and 3-(tert-butoxycarbonylamino) aniline based on the reactivity differences of the three chlorine atoms on the triazine ring. The optimized
开发了一种实用的大规模合成方法,用于制备以化合物2为例的N,N′-双(4,6-二取代的1,3,5-三嗪-2-基)-4-氨基苯乙胺衍生物。基于三嗪环上三个氯原子的反应性差异,该途径是六步过程,从市售的氰尿酰氯和3-(叔丁氧基羰基氨基)苯胺开始。按比例扩大优化程序,以最终产品2的总收率达到61%和99.9%的纯度。这些低分子量化合物模拟蛋白质A与IgG抗体结合的能力。
