methyl (Z)-2-[(benzyloxy)carbonyl]amino-3-(3-[(tert-butoxycarbonyl)amino]methyl-4-methoxyphenyl)-2-propenoate → Methyl 2-amino-3-(3-[(tert-butoxycarbonyl)amino]methyl-4-methoxyphenyl)propanoate

Participants

Reaction Steps

5 g of methyl (Z)-2-[(benzyloxy)carbonyl]amino-3-(3-[(tert-butoxycarbonyl)amino]methyl-4-methoxyphenyl)-2-propenoate was dissolved in methanol. 0.7 g of 10% palladium-carbon was added thereto, followed by stirring for 16 hours in a hydrogen atmosphere. The reaction solution was filtered and evaporated. The residue was purified by silica gel column chromatography (ethyl acetate), to give 3.4 g of methyl 2-amino-3-(3-[(tert-butoxycarbonyl)amino]methyl-4-methoxyphenyl)propanoate was obtained.
