Versuchsvorschrift

A mixture of Example 32B (87 mg, 0.2 mmol), (R)-tert-butyl 2-{[tert-butyl(dimethyl)silyl]oxy}-1-(hydroxymethyl)ethylcarbamate (62 mg, 0.2 mmol) and 1N potassium tert-butoxide in THF (0.2 mL, 0.2 mmol) in THF (10 mL) was stirred at room temperature for 1 hour. The mixture was concentrated under reduced pressure and the residue was partitioned between EtOAc and water. The organic layer was washed with brine, dried with MgSO4 and concentrated under reduced pressure to afford 100 mg of the title compound. MS (DCI/NH3) m/z 716 (M+H)+.
