Versuchsvorschrift

The above amide (45.54 g; 0.101 mmol) was dissolved in tetrahydrofuran (1000 mL) and methanol (1200 mL). A solution of sodium hydroxide (20.26 g; 0.507 mol) in water (500 mL) was added. Mixture was stirred for 2 hrs at room temperature and then it was concentrated in vacuo. The residue was separated between chloroform (1200 mL) and water (800 mL). Aqueous layer was extracted with chloroform (3×400 mL). Organic layers were combined and dried over anhydrous magnesium sulfate. Evaporation of the solvent yielded brown oil, which was dried for 3 days in vacuo to give the title product as beige solid.
