Process research, development, and manufacture of TP-808 (1), a key intermediate for the discovery and manufacture of tetracycline analogues, is described. The process used for the preparation of 1 avoids chromatographic purifications and has been substantially improved over the previously reported preparation. The robustness of the process was demonstrated in a 76.1 kg manufacturing campaign with
描述了TP-808(1)(发现和制造四环素类似物的关键中间体)的工艺研究,开发和制造。用于制备1的方法避免了色谱纯化,并且相对于先前报道的制备已得到实质性改进。在76.1千克的生产活动中证明了该过程的稳健性,总产率为56%。
