実験手順
To a solution of 0.047 g (0.11 mmol) of [3′-(3-chloro-benzoylamino)-5′-cyano-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-yl]-acetic acid ethyl ester in a mixture of THF (5 mL) and MeOH (2 mL) is added water (1 mL) and 0.013 g (0.55 mmol) of lithium hydroxide. The reaction mixture is stirred at room temperature for three days. The solvent is removed under reduced pressure and the residue is taken back up into water. The pH of the resulting aqueous solution is adjusted to approximately pH2 by adding concentrated hydrochloric acid which results in a solid precipitating from solution. The formed precipitate is collected by filtration, washed with water, and dried under vacuum to give 0.035 g (80%) of [3′-(3-chloro-benzoylamino)-5′-cyano-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-yl]-acetic acid as yellow solid.
