摘要:
This invention provides a convenient and industrially advantageous process producing amine derivatives having the action of inhibiting the secretion and accumulation of amyloid &bgr; 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 &bgr; protein can be obtained in high yield.
