Arylkylamine spirofuropyridines useful in therapy

Abstract

A compound of formula I,wherein NRRis attached at the 5- or 6-position of the furopyridine ring; R is hydrogen, C–Calkyl, or COR; Ris (CH)Ar, CHCH═CHAr, or CHC≡CAr; n is 0 to 3; A is N or NO; Ar is a 5- or 6-membered aromatic or heteroaromatic ring which contains zero to four nitrogen atoms, zero to one oxygen atoms, and zero to one sulfur atoms; or an 8-, 9- or 10-membered fused aromatic or heteroaromatic ring system containing zero to four nitrogen atoms, zero to one oxygen atoms, and zero to one sulfur, any of which may optionally be substituted with one to two substitutents independently selected from: halogen, trifluoromethyl, or C–Calkyl; Ris hydrogen, C–Calkyl, C–Calkoxy or phenyl ring optionally substituted with one to three of the following substituents: halogen, C–Calkyl, C–Calkenyl, C–Calkynyl, OH; OC–Calkyl, COR, —CN, —NO, —NRR, or —CF; R, Rand Rmay be hydrogen, C–Calkyl, or phenyl ring optionally substituted with one to three of the following substituents: halogen, C–Calkyl, C–Calkenyl, C–Calkynyl, OH; OC–Calkyl, —CN, —NO, or —CF; and enantiomers thereof, and pharmaceutically acceptable salts thereof, processes for preparing them, composition containing them, and their use in therapy, especially in the treatment or prophylaxis of psychotic disorders and intellectual impairment disorders.
