Versuchsvorschrift
A solution of compound 55e (80.2 mg, 0.3 mmol), and LiOH.H2O (50.4 mg, 1.2 mmol) in THF/H2O (1.2/1.2 mL) was stirred at room temperature overnight. The resulting mixture was concentrated and diluted with water. The water layer was acidified with 1N aqueous HCl to pH ˜4 and extracted with CH2Cl2. The organic solution was dried over Na2SO4 and concentrated to give 55f (60 mg), which was used in the next reaction without further purification. MS m/z (M+H+) 254.1.
