Reaction Steps

In 2 ml of 90% methanol was dissolved 0.20 g of ethyl 5-[[5-[(4-acetyl-3-hydroxy-2-propylbenzyl)thio]-1,3,4-thiadiazol-2-yl]thio]valerate obtained in Example 9 with heating at 60° C. Further 1.5 ml of a 1N aqueous sodium hydroxide solution was added to the solution followed by stirring at 60° C. for 30 minutes An aqueous sodium hydroxide solution and ethyl acetate were added to the reaction solution to fractionate. The aqueous phase was made acidic with 2N hydrochloric acid and extracted with ethyl acetate The extract was washed with, in sequence, water, a saturated aqueous sodium chloride solution and then water and, dried over anhydrous magnesium sulfate. The solvent was then distilled off to give 0.18 g of oily 5-[[5-[(4-acetyl-3-hydroxy-2-propylbenzyl)thio]-1,3,4-thiadiazol- 2-yl]thio]valeric acid.
