실험 절차

Heat a solution of 4-(5-amino-pyridin-2-yl)-piperazine-1-carboxylic acid tert-butyl ester (Preparation 4, 1.05 equiv, 0.5845 g), [5-(1-methyl-cyclopropyl)-2-p-tolyl-2H-pyrazol-3-yl]-carbamic acid 2,2,2-trichloroethyl ester (Preparation 39, 1.0 equiv, 0.8054 g) and diisopropylethylamine (2 equiv, 0.7 mL) in DMSO (0.25 M, 8 mL) to 60° C. for 6 hours. Cool the resulting mixture to ambient temperature, and add water (20 mL). Extract with EtOAc (2×25 mL), then wash the combined organic phases with water (10 mL) and saturated aq. sodium chloride solution (10 mL). Dry over MgSO4, then subject residue to silica gel chromatography eluting with a gradient 2 M ammonia-methanol in dichloromethane. LCMS(ES+): m/z=532.3 [M+H].
