Versuchsvorschrift
43 mg (0.07 mmol) of di-tert-butyl (4S)-4-(4-{trans-[3-(benzyloxy)cyclobutyl]oxy}benzyl)-N-(tert-butoxycarbonyl)-L-glutamate were dissolved in 10 mL of methanol and under argon atmosphere palladium (10% on charcoal) was added and the suspension hydrogenated overnight at room temperature. The reaction mixture was filtered, the solvent evaporated and the residue was chromatographed on silica gel using a hexane/ethyl acetate gradient, and the appropriate fractions were combined and concentrated.
