Abstract:
The present invention relates to a compound of formula (I): wherein A and A′ independently represent a phenylene group or a pyridylene group; R 2  is a hydrogen atom or a (C 1 -C 4 )alkyl group; R 3  is a 2-pyridyl group, 3-pyridyl group, a 4-pyridyl group, a 2-pyrimidinyl group, a 4-pyrimidinyl group or a 5-pyrimidinyl group; R 4  is a carbonyl group or a sulfonyl group; and R 5  is a —NH—(CH 2 ) a —NR 6 R 7  group or a 4-methylpiperazinyl group, with a being an integer from 1 to 4, R 6  and R 7  representing independently a (C 1 -C 4 )alkyl group, or R 6  and R 7  together with the nitrogen atom to which they are linked forming a heterocycle group which is chosen among a 4-methylpiperazinyl group, a morpholino group, a pyrrolidinyl group and a piperidino group; or any one of its pharmaceutically acceptable salt.

Claim (Index 13):
A process for the preparation of compounds of formula (I) according to  claim 1 , comprising:\n reacting a compound of formula (II) wherein R 2 and R 3  are as defined in  claim 1 , with a compound of formula (III) wherein X is a chlorine atom, an iodine atom or a bromine atom, and R 4  and R 5  are as defined in  claim 1 , wherein the reaction takes place in a protic solvent, in presence of an inorganic base, in the presence of a diphosphine and of an organometallic catalyst, the temperature being increased from 80 to 120\u00b0 C. under an inert gas.
