Claim:
A process for the preparation of a compound of formula (I): in which: W represents a group —COOR or a radical —CN; R 1 represents a hydrogen or halogen atom or a (C 1 -C 4 ) alkyl group; R 2 , R 3 , R 4 , R 5 , R 6 and R 7 each represent, independently of one another a hydrogen or halogen atom or a (C 1 -C 4 ) alkyl, (C 1 -C 4 ) alkoxy or trifluoromethyl group; R represents a (C 1 -C 4 ) alkyl or benzyl group; wherein a phenylboronic acid derivative of formula (II): in which R 5 , R 6 and R 7 are as defined above for (I), is reacted with a compound of formula (III): in which: W, R 1 , R 2 , R 3 and R 4 are as defined above for (I); Y represents a (C 1 -C 4 )alkyl group, a (C 1 -C 4 ) perfluoroalkyl group or a phenyl group that is un-substituted or substituted with a methyl, chloro or nitro group.
