Procedure

0.446 g of methyl cis-4-[4-(5-cyclopentyloxymethyl[1.3.4]thiadiazol-2-ylcarbamoyl)-phenoxy]cyclohexanecarboxylate (0.97 mmol, 1 eq.) is placed in 10 mL of THF with stirring, at room temperature, 0.111 g of lithium hydroxide monohydrate (2.64 mmol, 2.7 eq.) dissolved in 10 mL of water is added and the mixture is stirred for 36 hours and left to stand for 48 hours. Aqueous 1N hydrochloric acid solution is then added to acidic pH. The precipitate formed is filtered off and washed with water and with ethanol. 0.320 g of cis-4-[4-(5-cyclopentyloxymethyl[1.3.4]thiadiazol-2-ylcarbamoyl)phenoxy]-cyclohexanecarboxylic acid is obtained.
