Reaction Steps

2.49 g (5.14 mmol) of t-butyl 4,9-bisbenzyloxy-carbonyl-4,9-diazanonanoate was dissolved in 20 ml of methanol and 0.3 g of palladium black was added thereto. The obtained mixture was reduced at room temperature under atmospheric pressure in a hydrogen gas stream for three hours. After filtering off the catalyst, the filtrate was concentrated under reduced pressure to thereby give 1.11 g of the aimed compound in the form of an oily product (yield: 100%).
