PROCEDURE

实验过程

A solution of 1-benzyl 4-tert-butyl ((1S)-1-{[1-methyl-5-(tritylamino)-1H-pyrazol-4-yl]carbamoyl}tetramethylene)biscarbamate (6.4 g) in methanol (100 ml) was treated with 10% palladium on carbon (1.0 g) under a hydrogen atmosphere at room temperature for 6 days. After the catalyst was filtered off, the filtrate was concentrated in vacuo. The residue was triturated with ether and dried in vacuo to give tert-butyl (4S)-4-amino-5-{[1-methyl-5-(tritylamino)-1H-pyrazol-4-yl]amino}-5-oxopentylcarbamate (2.2 g) as a solid.
