The compounds of formula (I), or its pharmaceutically acceptable salts, or any stereoisomer or mixture thereof, wherein: R1 and R1' are both H, or R1 and R1' are taken together forming a biradical of formula -CH2-C(R4)=CH-; R2 and R3 are radical independently selected from the group consisting of H, F, CI and (C1-C4)-alkyl; R4 is a (C1-C2)-alkyl radical; and n is an integer from 2 to 15, are useful for the treatment of a neurodegenerative disorder such as Alzheimer's disease.
