Reaction Steps
(5-{2-[(N-Cyclopropanecarbonyl-N-ethyl-amino)-methyl]-4-fluoro-phenyl}-pyridin-3-yl)-acetic acid ethyl ester (0.202 g, 0.53 mmol) was dissolved in THF (5.25 mL) and treated with 1N aqueous LiOH (2.63 mL, 2.63 mmol) and a small amount of MeOH. The reaction was stirred at 35° C. for 30 minutes. The mixture was concentrated, and the residue was diluted with H2O and washed with EtOAc. The aqueous layer was acidified with 1N aqueous HCl to pH 6 and extracted with EtOAc, and the combined organic layers were washed with H2O and brine, and then dried over Na2SO4, filtered, and concentrated to give Compound 23.
