Reaction Steps

In 2 ml of 90% methanol was suspended 0.14 g of ethyl [[3-[[5-[(4-acetyl-3-hydroxy-2-propylbenzyl)thio]-1,3,4-thiadiazol-2-yl]thio]propyl]thio]acetate obtained in Example 25. Further 1 ml of a 1N aqueous sodium hydroxide solution was added to the suspension followed by stirring at room temperature for 45 minutes An aqueous sodium hydroxide solution and ethyl acetate were added to the reaction mixture to fractionate. The aqueous phase was made acidic with 1N hydrochloric acid and extracted with ethyl acetate. After the extract was washed with water and then dried over anhydrous magnesium sulfate, the solvent was distilled off. The residue was applied to silica gel column chromatography. Elution with a solvent mixture of hexane-ethyl acetate (1:2) gave 0.14 g of oily [[3-[[5-[(4-acetyl-3-hydroxy-2-propylbenzyl)thio]-1,3,4-thiadiazol-2-yl]thio]propyl]thio]acetic acid.
