Reaction Steps

To a mixture of 0.080 g (0.23 mmol) of (3′-amino-6′-methanesulfonyl-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-yl)-acetic acid ethyl ester in acetonitrile (5 mL) is added 0.12 mL (0.70 mmol) of N,N-diisopropylethylamine followed by 0.032 mL (0.28 mmol) of 3-chlorobenzoyl chloride. The mixture is heated at 80° C. for 1 h then an additional 0.096 mL (0.84 mmol) of 3-chlorobenzoyl chloride is added. The mixture is stirred at 80° C. for an additional 10 minutes then cooled to room temperature and concentrated under reduced pressure. The residue is purified by flash silica gel chromatography to provide 0.055 g (49%) of [3′-(3-chloro-benzoylamino)-6′-methanesulfonyl-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-yl]-acetic acid ethyl ester as a colorless foam.
