実験手順

1.62 g (2.22 mmol) (R)-1-(4-benzyloxy-3,5-dimethyl-benzyl)-2-(4-benzyl-piperazin-1-yl)-2-oxo-ethyl 4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carboxylate in 40 mL MeOH were combined with 150 mg 10% Pd/C and hydrogenated at RT and 3 bar hydrogen until the reaction came to an end. The catalyst was removed by suction filtering and the solvent was concentrated by evaporation i. vac. The residue was purified by chromatography (silica gel, EtOAc/MeOH/NH3 85:13.5:1.5).
