실험 절차

Tert-butyl 4-{3-[(3R)-3-({(1S)-1-[5-(benzyloxy)pyridin-3-yl]-3-tert-butoxy-3-oxopropyl}carbamoyl)piperidin-1-yl]-3-oxopropyl}piperidine-1-carboxylate (1.69 g, 2.49 mmol) in ethyl acetate (73 mL) and methanol (12 mL) was stirred for 20 hours at room temperature under a hydrogen atmosphere in the presence of palladium on charcoal (10%, 170 mg). The suspension was filtrated through celite, which were washed thoroughly with methanol. The solution was concentrated under reduced pressure and the residue was purified by chromatography on silica gel (methanol in ethyl acetate 0 to 15%) to yield 1.37 g of Tert-butyl 4-{3-[(3R)-3-{[(1S)-3-tert-butoxy-1-(5-hydroxypyridin-3-yl)-3-oxopropyl]carbamoyl}piperidin-1-yl]-3-oxopropyl}piperidine-1-carboxylate.
