Procedure
To a solution of 0.10 g (0.29 mmol) of (3′-amino-5′-phenyl-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-yl)-acetic acid ethyl ester in acetonitrile (5 mL) is added 0.041 mL (0.32 mmol) of 3-chlorobenzoyl chloride. The mixture is stirred at room temperature for 2 hours then concentrated under reduced pressure. A saturated aqueous solution of ammonium chloride is added and the mixture is extracted with ethyl acetate. The combined organic phase is dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue is purified by flash silica gel chromatography to provide 0.115 g (81%) of [3′-(3-chloro-benzoylamino)-5′-phenyl-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-yl]-acetic acid ethyl ester as a colorless foam.
