Reaction Steps

In 20 ml of methanol is dissolved 0.5 g of N-[N-[(S)-5-(1-benzyloxycarbonyl-4-piperidyl)-1-carboxypentyl]-L-alanyl]-N-(indan-2-yl)glycine tert-butyl ester, and a catalytic reduction is carried out at ambient temperature and under atmospheric pressure using 10% palladium-carbon (50% wet., 0.5 g) as a catalyst. After stirring at room temperature for 4 hours, the catalyst is filtered off, and the filtrate is concentrated under reduced pressure to give 0.28 g of N-[N-[(S)-5-(4-piperidyl)-1-carboxypentyl]-L-alanyl]-N-(indan-2-yl)glycine tert-butyl ester as a colorless powder.
