In 100 ml of methanol was dissolved 3.73 g of N-benzyloxycarbonyl-L-leucyl-L-argininal dibutyl acetal obtained. In nitrogen atmosphere, 1 g of palladium black was added to the solution and the mixture was subjected to catalytic hydrogenation at room temperature for 2 hours. After palladium black was removed by filtration, the filtrate was concentrated under reduced pressure to give 2.75 g of L-leucyl-L-argininal dibutyl acetal.
