Conditions

Temperature: 80 °C

Procedure

To N-benzyl-N-(1-tert-butoxycarbonyl-1,2,3,6-tetrahydropyridin-4-yl)-2-iodobenzamide (2.4 g) dissolved in acetonitrile, palladium acetate (80 mg), triphenylphosphine (187 mg), anhydrous K2CO3 (987 mg) and tetraethylammonium chloride (591 mg) were added and stirred at 80° C. for 6 hours. The reaction mixture was poured into water and extracted with ethyl acetate. The ethyl acetate layer was dried over anhydrous Na2SO4 and concentrated. The residue was purified by column chromatography on silica gel (hexane/ethyl acetate=4/1 to 1/2) to give the subject compound (1.64 g).
