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 33):
A process for preparing a compound of formula (I) according to  claim 15  wherein at least one of R 1  and R 2  is 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; 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 (a2) coupling of a compound of formula (I) according to  claim 15  wherein at least one of R 1  and R 2  is a halogen atom,\n with a boronic acid derivative of formula R 3 \u2014B(R 4 ) 2  or R 3 \u2014BF 3 \u2212 K +  wherein R 3  is 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, and R 4  is a (C 1 -C 6 )alkyl, OH or (C 1 -C 6 )alkoxy group, \n or with a zinc derivative of formula R 3 \u2014Zn-Hal wherein R 3  is as defined above and Hal is a halogen atom, \n or with a stannane derivative of formula R 3 \u2014SnA 1 A 2 A 3  wherein R 3  is as defined above and A 1 , A 2  and A 3 , which can be identical or different, are each a (C 1 -C 6 )alkyl group, \n or with a magnesium derivative of formula R 3 \u2014Mg-Hal wherein R 3  and Hal are as defined above, \n or with a silicon derivative of formula R 3 \u2014SiMe 2 OH, R 3 \u2014SiF 3  or R 3 \u2014Si(OA 1 )(OA 2 )(OA 3 ) wherein R 3 , A 1 , A 2  and A 3  are as defined above, \n or with an alkyne of formula R\u2032\u2014C\u2261CH wherein R\u2032 is a protecting group or a linear or branched, saturated or unsaturated hydrocarbon chain having from 1 to 8 carbon atoms, \n \n (b2) when step (a2) was performed with an alkyne of formula R\u2032\u2014C\u2261CH wherein R\u2032 is a protecting group, deprotection of the protecting group of the alkyne function, and \n (c2) 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).
