実験手順

Add DIEA (2 equiv.) to a solution of [4-(5-amino-3-methyl-pyridin-2-yl)-piperazin-1-yl]-(2,6-difluoro-phenyl)-methanone (400 mg, 1.205 mmol) and [5-(2-fluoro-1,1-dimethyl-ethyl)-2-p-tolyl-2H-pyrazol-3-yl]-carbamic acid 2,2,2-trichloro-ethyl ester (1 equiv) in acetonitrile (12 mL). Stir the mixture at 80° C. in a sealed tube. After 4 days, remove solvent. Dilute crude with DCM, extract with water, and dry over Na2SO4. Filter and remove solvent under reduced pressure. Subject solid to silica gel chromatography, eluting with hexane/acetone 3:1 to obtain 352 mg of 1-{6-[4-(2,6-difluoro-benzoyl)-piperazin-1-yl]-5-methyl-pyridin-3-yl}-3-[5-(2-fluoro-1,1-dimethyl-ethyl)-2-p-tolyl-2H-pyrazol-3-yl]-urea as a white solid (48% yield). ES+(m/z): 606 [M+1]
