실험 절차

To a suspension of tert-butyl 3-aminopropylcarbamate (366 mg) and 3-ethoxy-4-{[1-methyl-5-(tritylamino)-1H-pyrazol-4-yl]amino}-3-cyclobutene-1,2-dione (67.0 mg) in ethanol (30 ml) was added triethylamine (0.195 ml), and the mixture was stirred under reflux for 3 hours. To the reaction mixture were added diethyl ether (40 ml) and hexane (10 ml). The crystalline precipitate was collected by filtration and dried in vacuo to give tert-butyl {3-[(2-{[1-methyl-5-(tritylamino)-1H-pyrazol-4-yl]amino}-3,4-dioxo-1-cyclobuten-1-yl)amino]propyl}carbamate (788 mg) as a solid.
