It has been found that aryl amines can be directly protected as their Boc derivatives by treatment of the amine with two equivalents of NaHMDS in THF followed by one equivalent of di-t-butyldicarbonate. This procedure works on a wide variety of both electron-rich and electron-deficient aryl amines.
业已发现,芳基胺可直接保护它们的Boc衍生物由治疗的胺在THF加入NaHMDS的两个当量接着一个当量的二-吨-butyldicarbonate。该方法适用于多种富电子和缺电子的芳基胺。
