Procedure

By carrying out the reaction as in Stage C of Example 45, but from 1 g of methyl (3aRS,4SR,7aRS)-2-benzyl-7-iodo-4-phenyl-2,3,3a,4,5,7a-hexahydro-1H-isoindole-3a-carboxylate in 20 cm3 of toluene, from 120 mg of tetrakis(triphenylphosphine)palladium, from 0.46 g of 4-bromophenylboronic acid in 10 cm3 of methanol and from 15 cm3 of a 2N aqueous sodium carbonate solution at reflux for eighteen hours, 0.77 g (73%) of methyl (3aRS,4SR,7aRS)-2-benzyl-7-(4-bromophenyl)-4-phenyl-2,3,3a,4,5,7a-hexahydro-1H-isoindole-3a-carboxylate was obtained, after purification by flash chromatography on silica gel (230-400 mesh), elution was carried out with a mixture of cyclohexane and of ethyl acetate (90/10 by volume), in the form of a white foam, the characteristic of which was as follows:
