実験手順

To a suspension of phenyl [1-methyl-5-(tritylamino)-1H-pyrazol-4-yl]carbamate (4.6 g) in N,N-dimethylformamide (32 ml) were added triethylamine (1.08 g) and tertbutyl 1-piperazinecarboxylate (1.99 g). The reaction mixture was stirred for 3 hours and poured into water. The mixture was extracted with ethyl acetate, and the organic layer was concentrated in vacuo. The residue was purified by column chromatography on silica gel (ethyl acetate→ethyl acetate:ethanol=20:1) to give tert-butyl 4-({[1-methyl-5-(tritylamino)-1H-pyrazol-4-yl]amino}carbonyl)-1-piperazinecarboxylate (4.7 g)
