Procedure
By carrying out the reaction as in Stage C of Example 45, but from 1.35 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 340 mg of tetrakis(triphenylphosphine)palladium, from 0.38 g of trimer anhydride of 4-ethylphenylboronic acid in 10 cm3 of methanol and from 15 cm3 of a 2N aqueous sodium carbonate solution at reflux for eighteen hours, 0.92 g (72%) of methyl(3aRS,4SR,7aRS)-2-benzyl-7-(4-ethylphenyl)-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 being carried out with a mixture of cyclohexane and of ethyl acetate (90/10 by volume), in the form of a viscous yellow oil, the characteristic of which was as follows:
