The present invention is concerned with fluorobenzamide derivatives of the general
formula Wherein R1 is hydrogen, (C1-C6)-alkyl or
hydroxy-(C1-C6)-alkyl; R2 is (C1-C6)-alkyl, -CO-NR8R9,
-(CH2)n-NR8R9, -(CH2)P-OR8,
or -(CH2)n-CN; R3 is selected from hydrogen,
halogen, halogen-(C1-C6)-alkyl, cyano, C1
-C6-alkoxy or halogen-(C1-C6)-alkoxy; R4,
R5, R6 and R7 are hydrogen or fluoro, and at least
one of R4, R5, R6 and R7 is fluoro; R8
and R9 independently from each other are hydrogen or (C1-C6)-alkyl;
m is 1, 2 or 3; n is 0, 1, 2 or 3; and p is 1 or 2; as well as their pharmaceutically acceptable
salts. The compounds of general formula I are selective monoamine oxidase B inhibitors
and therefore they are suitable for the treatment of Alzheimer's disease
or senile dementia.
