This invention provides a convenient and industrially advantageous process producing amine derivatives having the action of inhibiting the secretion and accumulation of amyloid β protein.
In Compound (I), the ether linkage is selectively cleaved without cleaving the amide linkage present in the same molecule and tertiary amines are not converted into quaternary salts, and thus Amine Derivative (V) with good qualities having the action of inhibiting the secretion and accumulation of amyloid β protein can be obtained in high yield.
本发明提供了一种生产具有抑制淀粉样β蛋白分泌和积聚作用的胺衍
生物的方便且具有工业优势的工艺。
在化合物(I)中,醚键被选择性地裂解,而不会裂解存在于同一分子中的酰胺键,叔胺也不会转化为季盐,因此可以高产率地获得具有抑制淀粉样β蛋白分泌和积累作用的优质胺衍
生物(V)。
