実験手順
A mixture of intermediate (29) (0.0036 mol), tributyl-2-furanyl-stannane (0.029 mol), PdCl2(PPh3)2 (0.0007 mol) and Na2CO3 (0.0576 mol) in dioxane (30 ml) was stirred and refluxed for 1 hour. Water was addedd. The mixture was extracted with ethyl acetate. The organic layer was separated, dried, filtered, and the solvent was evaporated. The residue was purified by column chromatography over silica gel (eluent: cyclohexane/ethyl acetate 80/20). The pure fractions were collected and the solvent was evaporated, yielding 4-[4-[[2-(2-furanyl)benzoyl]amino]phenyl]-α-phenyl-1-piperazineacetic acid, methyl ester (intermediate 30, mp. 90° C.).
