실험 절차

Through a suspension of 4-amino-3,3-difluoro-piperidine-1-carboxylic acid tert-butyl ester (90 mg, 381 μmol), 2-bromo-8-(2,3,4-trifluorophenyl)-[1,2,4]triazolo[1,5-a]pyridine (prepared in analogy to example 66a-d, 162 mg, 495 μmol), tris(dibenzylideneacetone)dipalladium(0) chloroform adduct (15.8 mg, 15.2 μmol), sodium phenoxide (65.2 mg, 533 μmol) and 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (17.6 mg, 30.5 μmol) in dry dioxane (5.0 mL) was bubbled argon for 5 minutes, then heated to 160° C. in the microwave for 60 minutes. The catalyst was filtered off, washed with CH2Cl2 and the solvents evaporated. The residue was purified by flash chromatography (silica gel, 70 g, 0% to 100% EtOAc in heptane). The title compound was obtained as orange solid (27 mg, 15%).
