実験手順

150 mg of methyl cis-4-{4-[5-(3-chlorophenyl)[1.3.4]thiadiazol-2-ylcarbamoyl]phenoxy}-cyclohexanecarboxylate (0.32 mmol, 1 eq.) is placed in 1 mL of tetrahydrofuran. 27 mg of lithium hydroxide monohydrate (0.64 mmol, 2 eq.) dissolved in 1 mL are added and stirring is continued for 18 hours. The reaction medium is diluted with water, washed with ethyl acetate and acidified with aqueous 6% sulfur dioxide solution. The solid obtained is filtered off by suction and washed successively with water, ethanol and diethyl ether. 96 mg of cis-4-{4-[5-(3-chlorophenyl)[1.3.4]thiadiazol-2-ylcarbamoyl]-phenoxy}cyclohexanecarboxylic acid are obtained.
