Reaction Steps

A solution of 2.50 g (4.38 mmol) (R)-2-(4-benzyloxy-3,5-dimethyl-phenyl)-1-carboxy-ethyl 4-(5-oxo-3-phenyl-4,5-dihydro-1,2,4-triazol-1-yl)-piperidine-1-carboxylate in 50 mL DCM was combined with 250 mg 10% Pd/C and hydrogenated at RT and 3 bar hydrogen pressure for 4.5 h. To complete the reaction a further 250 mg of catalyst were added, the mixture was hydrogenated for 12 h at 40° C., combined with 25 mL THF and 250 mg catalyst and hydrogenated for a further 12 h at 40° C. The catalyst was removed by suction filtering and the filtrate was concentrated by evaporation i. vac. The residue was stirred with DIPE, suction filtered and dried.
