실험 절차
A solution of lithium hydroxide (0.053 g, 1.26 mmol) in water (1 mL) was added dropwise to a stirred solution of methyl {(3S)-1-[5-(adamantan-1-ylcarbamoyl)-6-(propylthio)pyridin-2-yl]piperidin-3-yl}acetate (Intermediate 73, 204 mg, 0.42 mmol) in MeOH (3 mL) and THF (2 mL) at 18° C., over a period of 1 minute. The resulting solution was stirred at 18° C. for 20 hours. The reaction mixture was adjusted to pH 4.5 with 2M HCl and the reaction mixture was diluted with EtOAc (50 mL), and washed sequentially with water (20 mL) and saturated brine (20 mL). The organic layer was dried over MgSO4, filtered and evaporated to afford {(3S)-1-[5-(adamantan-1-ylcarbamoyl)-6-(propylthio)pyridin-2-yl]piperidin-3-yl}acetic acid (180 mg, 91%), as a white solid.
