HCID 67274143, compound → (R)-2-[4-(1-ethoxycarbonylmethyl-piperidin-4-yl)-piperazin-1-yl]-1-(4-hydroxy-3,5-dimethyl-benzyl)-2-oxo-ethyl 4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carboxylate

Participants

Reaction Steps

2.00 g (2.47 mmol) of (R)-1-(4-benzyloxy-3,5-dimethyl-benzyl)-2-[4-(1-ethoxycarbonylmethyl-piperidin-4-yl)-piperazin-1-yl]-2-oxo-ethyl 4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carboxylate in 25 mL EtOH were combined with 200 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 reacted further without any purification by chromatography.
