Abstract

PURPOSE:To provide the subject new chromanyloxyalkylamine derivative or its salt remarkably excellent in selective affinity to 5-HT1A receptor and useful for preventing or improving various kinds of 5-HT nervous system-related diseases. CONSTITUTION:The chromanyloxyalkylamine derivative represented by formula I (R<1> is H or a lower alkyl; R<2> is a lower alkoxy; Y is a lower alkylene) or its salt, e.g. N-[2-(6-fluoro-2-methyl-8-chromanyloxy)ethyl]-p-methylphenethylamine hydrochloric acid slat 0.25 hydrate of formula IV. The compound of formula I is obtained by reacting a compound of formula II (X is an alkylactivating group such as a halogen or methylsulfonyloxy) with a compound of formula III (Z is an amino-protecting group such as H or benzyl).
