실험 절차

tert-Butyl 4-(4-((4-chloro-5-(trifluoromethyl)pyrimidin-2-yl)amino)phenyl)piperidine-1-carboxylate (I43) (140 mg, 0.306 mmol), ethyl 2-(3-ethynylpyrazin-2-yl)acetate (I101) (64 mg, 0.34 mmol), bis(triphenylphosphine)palladium(II) chloride (11 mg, 5 mol %) and DMF (2 mL) were loaded into a microwave tube and degassed with a nitrogen for ten minutes. Copper(I) iodide (3 mg, 5 mol %) and triethylamine (0.192 mL, 1.38 mmol) were added under nitrogen and the resulting mixture heated under microwave irradiation (120° C./15 minutes). The cooled mixture was concentrated, and the residue evaporated onto silica gel. Chromatography (12 g silica cartridge, 0-100% ethyl acetate/petroleum benzine 40-60° C.) gave the title compound (I102) (95.5 mg, 52% yield) as a yellow solid; 1H NMR (400 MHz, d6-DMSO) δ 10.47 (s, 1H), 8.87 (d, J=0.5 Hz, 1H), 8.76-8.71 (m, 2H), 7.63 (d, J=8.6 Hz, 2H), 7.23 (d, J=8.6 Hz, 2H), 4.15-3.99 (m, 6H), 2.80 (s, 2H), 2.70-2.63 (m, 1H), 1.80-1.70 (m, 2H), 1.55-1.44 (m, 2H), 1.42 (s, 9H), 1.14 (t, J=7.1 Hz, 3H). LCMS Method C: rt 6.73 min; m/z 633.1 [M+Na]+, 555.0 [M-tBu+2H]+, 511.1 [M-Boc+2H]+; m/z 609.1 [M−H]−.
