実験手順

A mixture of intermediate (1) (0.012 mol), N-allyl-phthalimide (0.012 mol), palladium(II) acetate (0.001 mol) and triethylamine (0.024 mol) was stirred at 100° C. for 12 hours in a bomber, then dissolved in DCM and washed with K2CO3 10%. The organic layer was separated, dried, filtered, and the solvent was evaporated. The residue was crystallized from ACN. The precipitate was filtered off and dried, yielding 3.2 g of N-[4-[(1E)-3-(1,3-dihydro-1,3-dioxo-2H-isoindol-2-yl)-1-propenyl]phenyl]-4′-(trifluoromethyl)-[1,1′-biphenyl]-2-carboxamide (intermediate 2; mp. 190° C.).
