Provided is a process for the preparation of t-butoxycarbonylamine compounds, which comprises using phosgene or a phosgene equivalent, t-butanol, and an organic base. Even when applied to a primary or secondary amine compound having low nucleophilicity, the process enables highly selective preparation of a t-butoxycarbonylamine compound at a low cost. In the process, a t-butoxycarbonylamine compound is prepared using: phosgene or a phosgene equivalent; t-butanol; an organic base; and either a primary or secondary amine compound or a primary or secondary ammonium salt.
提供了一种制备叔丁氧羰胺化合物的方法,包括使用光气或光气等效物、叔丁醇和有机碱。即使应用于具有低亲核性的初级或次级胺化合物,该方法也能以较低成本实现对叔丁氧羰胺化合物的高选择性制备。在该过程中,使用光气或光气等效物、叔丁醇、有机碱以及初级或次级胺化合物或初级或次级铵盐来制备叔丁氧羰胺化合物。
