Participants

Reaction Steps

To a mixture of 0.055 g (0.11 mmol) of [3′-(3-chloro-benzoylamino)-6′-methanesulfonyl-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-yl]-acetic acid ethyl ester in a 2:1 mixture of tetrahydrofuran:methanol (6 mL) is added 0.014 g (0.57 mmol) of lithium hydroxide as a solution in water (1 mL). The mixture is stirred overnight at room temperature then concentrated under reduced pressure. The residue is diluted with water and the pH of the mixture is adjusted to pH 2 by the addition of concentrated hydrochloric acid causing a solid to precipitate from solution. The formed precipitate is collected by filtration and dried to provide 0.023 g (44%) of [3′-(3-chloro-benzoylamino)-6′-methanesulfonyl-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-yl]-acetic acid as a yellow solid.
