Reaction Steps

To a suspension of 0.480 g (1.18 mmol) of 5′-chloro-3′-(3-chloro-benzoylamino)-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-carboxylic acid methyl ester in a 1:1 mixture of water:methanol (10 mL) is added 1.0 mL (2.5 mmol) of sodium hydroxide as a 10% aqueous solution. The mixture is stirred at room temperature overnight then concentrated under reduced pressure to remove volatile organics. The pH is adjusted to approximately pH 5 by the addition of a 2N solution of hydrochloric acid causing a solid to precipitate from solution. The material is collected by filtration, washed with water, and dried on the filter pad to provide 0.35 g (75%) of 5′-chloro-3′-(3-chloro-benzoylamino)-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-carboxylic acid as a light yellow solid.
