Abstract: The invention provides methods of treating a memory deficiency in a subject in need of such treatment, where the methods comprise administering to a subject an effective amount of a compound of formula (1): wherein: R1 is hydrogen, fluorine or a methoxyl group, R1 being in position 2, 3, 4 or 5 of the aromatic carbocycle; R2 is hydrogen or a methyl group; R3 is hydrogen, a methyl group or an ethyl group; and their pharmaceutically acceptable acid addition salt as well as the isomers and the tautomers thereof. The memory deficiency may be correlated with a memory deficiency induced by scopolamine.
