실험 절차

To a solution of {3-[5-(4-fluoro-phenyl)-3-(2,4,6-trifluoro-benzoyl)-2,3-dihydro-[1,3,4]thiadiazol-2-yl]-2-methoxy-phenoxy}-acetic acid methyl ester (2.47 mmol) in 30 mL of a mixture of THF and MeOH (3:2), is added LiOH (1 M) (25 mL). After stiffing for 12 hours the reaction is complete as determined by LC/MS. The reaction is diluted with ethyl acetate and water, washed with brine and dried over MgSO4 and the solvent is removed from the reaction mixture to yield {3-[5-(4-fluoro-phenyl)-3-(2,4,6-trifluoro-benzoyl)-2,3-dihydro-[1,3,4]thiadiazol-2-yl]-2-methoxy-phenoxy}-acetic acid: LC/MS (ES+): 521.1 (M+1)+.
