Procedure
yl-3-hydroxy-2-propylbenzyl)thio]-1,3,4-thiadiazol-2-yl]amino]-4-oxobutyrate obtained in Example 23. Further 2 ml of a 1N aqueous sodium hydroxide solution was added to the suspension followed by stirring at room temperature for 20 minutes An aqueous sodium hydroxide solution and ethyl acetate were added to the reaction mixture to fractionate. The aqueous phase was made acidic with a 1N hydrochloric acid and extracted with ethyl acetate. After the extract was dried over anhydrous magnesium sulfate, the solvent was distilled off The residue was recrystallized from isopropyl alcohol to give 0.11 g of 4-[[5-[(4-acetyl-3-hydroxy-2-propylbenzyl)thio]-1,3,4-thiadiazol-2-yl]amino]-4-oxobutyric acid.
