Abstract:
The invention relates to compounds of formula (I), particularly for the use thereof as a medicament, especially in the treatment or prevention of neurogenerative disorders. The invention also relates to the methods for producing said compounds, and to the pharmaceutical compositions containing same.

Claim (Index 31):
A process for preparing a compound of formula (I) according to  claim 15 , pyrido[3,2-f]quinoxaline, 2,3-dimethyl-pyrido[3,2-f]quinoxaline, 2,3,8-trimethyl-pyrido[3,2-f]quinoxaline or 2,3-diphenyl-pyrido[3,2-f]quinoxaline, comprising the following successive steps:\n (a1) coupling between an amino-quinoxaline of following formula (II): wherein R 1  and R 2  are each independently a hydrogen atom; a halogen atom; a linear or branched, saturated or unsaturated hydrocarbon chain having from 1 to 10 carbon atoms; an optionally substituted aryl; or an optionally substituted heteroaryl, with a propargyl halide of formula CH\u2261C\u2014CHR 2c Hal or CH\u2261C\u2014CR 2a R 2b Hal wherein:\n R 2a  and R 2b  are each independently a (C 1 -C 6 )alkyl group, \n R 2c  is a hydrogen atom or a (C 1 -C 6 )alkyl group, and \n Hal is a halogen atom, \n to give a compound of following formula (IIIa) or (IIIb): wherein R 1 , R 2 , R 2a , R 2b  and R 2c  are as defined above, (b1) cycloisomerization of the compound of formula (IIIa) or (IIIb) obtained in the preceding step and aromatization when   is a double bond to give a compound of formula (I), and (c1) optionally salification and/or solvation of the compound of formula (I) obtained in the preceding step to give a pharmaceutically acceptable salt and/or solvate of the compound of formula (I).
