Reaction Steps

A solution of N-[N-{2-[N-(hexahydro-1H-azepin-1-ylcarbonyl)-N-methylamino]ethyl}-N-methylaminocarbonyl]-L-phenylalanine benzyl ester (1.46 g) in methanol (20 ml) was hydrogenated over 10% palladium on carbon (146 mg) at 3 atmospheric pressure of hydrogen gas for 1 hour at ambient temperature. The solution was filtered and concentrated in vacuo to give N-[N-{2-[N-(hexahydro-1H-azepin-1-ylcarbonyl)-N-methylamino]ethyl}-N-methylaminocarbonyl]-L-phenylalanine (1.28 g) as an oil. Rf: 0.35 (chloroform:methanol:acetic acid, 16:1:1, V/V)
