1-Benzoyl-2-(3-chlorophenyl)-2,3-dihydro-pyridin-4-one (910 mg) was placed in an argon filled flask together with 42 mg Pd(II) TFA2, 108 mg binaphthyl-di-tert-butyl phosphine, 39 mg zinc powder, 203.4 mg zinc cyanide and 45 ml dimethylacetamide. The solution was degassed with argon and heated at 90° C. for eight hours. After cooling to room temperature, the mixture was filtered through glass fiber filter paper. The supernatant was basified with ammonium hydroxide and the resulting mixture was extracted with diethyl ether. The combined ether extracts were dried over sodium sulfate, filtered, and concentrated in vacuo. Chromatography of the residue gave 350 mg 3-(1-benzoyl-4-oxo-1,2,3,4-tetrahydro-pyridin-2-yl)-benzonitrile.
