Reaction Steps

To a mixture of 0.230 g (0.489 mmol) of [3′-(3-chloro-benzoylamino)-6′-trifluoromethyl-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-yl]-acetic acid ethyl ester in a 2:1 mixture of tetrahydrofuran:methanol (12 mL) is added 0.058 g (2.4 mmol) of lithium hydroxide as a solution in water (2 mL). The mixture is stirred at room temperature for 2 hours 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 0.21 g (quant) of [3′-(3-chloro-benzoylamino)-6′-trifluoromethyl-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-yl]-acetic acid as a white solid.
