実験手順

To a solution of ethyl (4-{[3-(5-{3-chloro-4-[(1-methylethyl)oxy]phenyl}-1,2,4-thiadiazol-3-yl)-2-ethylphenyl]methyl}-1-piperidinyl)acetate (D145) (80 mg, 0.148 mmol) in Isopropanol (6 mL) and Water (6.00 mL) was added NaOH (1.476 mL, 0.738 mmol). The reaction solution was heated to 90° C. for 2 hours. The solvent was removed in vacuo and the residue was acidified to pH=3-4, extracted with ethyl acetate. The combined organic phases were dried, concentrated and purified by Mass Directed AutoPrep to afford (4-{[3-(5-{3-chloro-4-[(1-methylethyl)oxy]phenyl}-1,2,4-thiadiazol-3-yl)-2-ethylphenyl]methyl}-1-piperidinyl)acetic acid (E105) (59 mg) as a TFA salt. δH (DMSO-d6, 400 MHz): 1.01 (3H, t), 1.28 (6H, d), 1.55 (2H, m), 1.72 (3H, m), 2.62 (2H, d), 2.87 (4H, m), 3.38 (2H, m), 3.98 (2H, s), 4.79 (1H, m), 7.23 (2H, m), 7.32 (1H, d), 7.59 (1H, dd), 7.95 (1H, dd), 8.07 (1H, d). δF (DMSO-d6, 376 MHz): −73.5. MS (ES): C27H32ClN3O3S requires 513.2. found 514.2 (M+H+).
