실험 절차

A mixture of tert-butyl 4-(4-((4-chloro-5-(trifluoromethyl)pyrimidin-2-yl)amino)phenyl)piperidine-1-carboxylate (K3) (193 mg, 0.422 mmol), PdCl2(PPh3)2 (15 mg, 0.021 mmol), t-Bu3PH.BF4 (6 mg, 0.021 mmol), CuI (4 mg, 0.021 mmol) and 2-(2-ethynylphenyl)butanamide (K1) (87 mg, 0.47 mmol) in DMF (3.0 mL) was degassed with nitrogen for 10 minutes. Et3N (1.0 mL) was added and the resulting mixture was heated under microwave irradiation at 120° C. for 20 minutes. The volatiles were removed under reduced pressure and the residue was adsorbed onto silica gel then purified by column chromatography (Biotage Isolera, SiO2 cartridge, 0-100% EtOAc in petroleum benzine 40-60° C.) to give the title compound A1 as a yellow solid (175 mg, 68%); 1H NMR (400 MHz, d6-DMSO) δ 10.39 (s, 1H), 8.88-8.76 (m, 1H), 7.67 (d, J=8.5 Hz, 2H), 7.63-7.47 (m, 3H), 7.37 (td, J=7.4, 1.6 Hz, 1H), 7.27-7.17 (m, 3H), 7.01 (s, 1H), 4.07 (s, 2H), 3.89 (dd, J=8.6, 6.4 Hz, 1H), 2.80 (br, 2H), 2.64 (J m, 1H), 1.98-1.90 (m, 1H), 1.74 (d, J=12.7 Hz, 2H), 1.70-1.60 (m, 1H), 1.55-1.44 (m, 2H), 1.42 (s, 9H), 0.87 (t, J=7.3 Hz, 3H). LCMS-A: rt 6.726 min; m/z 606 [M−H]−.
