実験手順
A solution of 2-benzyl 1-tert-butyl {(2S)-3-[(5-amino-1-methyl-1H-pyrazol-4-yl)amino]-3-oxo-1,2-propanediyl}biscarbamate (1.58 g) in tetrahydrofuran (28 ml) was treated with 10% palladium on carbon (0.75 g) under a hydrogen atmosphere for 2 hours at room temperature. After the catalyst was filtered off, the filtrate was concentrated in vacuo to give a crude oil, which was dissolved in tetrahydrofuran (28 ml). To the solution were added triethylamine (2.04 ml) and di-tert-butyl ({[(trifluoromethyl)sulfonyl]imino}methylene)biscarbamate (2.86 g) successively at room temperature. The mixture was stirred at room temperature overnight. To the reaction mixture was added water to quench the reaction. The mixture was extracted with ethyl acetate. The organic layer was washed with water and brine. The extract was dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo. The residue was purified by silica gel column chromatography to give di-tert-butyl {[((1S)-2-[(5-amino-1-methyl-1H-pyrazol-4-yl)amino]-1-{[(tert-butoxycarbonyl)amino]methyl}-2-oxoethyl)amino]methylylidene}biscarbamate (1.53 g) as an amorphous solid.
