Reaction Steps

To 8 ml of a solution of 830 mg of 4-[5,5-bis(acetylthiomethyl)pentyl]-5-methyl-2-(p-tolyl)oxazole in methanol, 8 ml of aqueous 1 N sodium hydroxide solution was added, and heated to reflux for 1 hour. The reaction solution was acidified with 1 N hydrochloric acid, extracted with dichloromethane and dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure to provide 635 mg of the objective compound as pale yellow oil.
