実験手順

A solution of tert-butyl 4-(4-((4-chloro-5-(trifluoromethyl)pyrimidin-2-yl)amino)phenyl)piperidine-1-carboxylate (K3) (262 mg, 0.574 mmol), PdCl2(PPh3)2 (20 mg, 0.029 mmol,) t-Bu3PH.BF4 (8 mg, 0.03 mmol), CuI (5 mg, 0.03 mmol) and methyl 1-(2-ethynylphenyl)cyclopropanecarboxylate (K2) (138 mg, 0.689 mmol) in DMF (5.0 mL) was degassed with nitrogen for 10 minutes. Et3N (1.0 mL) was added and the resulting mixture heated under microwave irradiation for 20 minutes at 120° C. The resulting mixture was adsorbed onto silica gel and purified by column chromatography (Biotage Isolera, SiO2 cartridge, 0-40% EtOAc in petroleum benzine 40-60° C.) to give the title compound A3 as a yellow solid (308 mg, 86%); 1H NMR (400 MHz, d6-DMSO) δ 10.37 (s, 1H), 8.79 (s, 1H), 7.67 (d, J=8.2 Hz, 2H), 7.60 (dd, J=7.6, 1.0 Hz, 1H), 7.54-7.38 (m, 3H), 7.21 (d, J=8.6 Hz, 2H), 4.07 (d, J=11.6 Hz, 2H), 3.52 (s, 3H), 2.80 (s, 2H), 2.65 (J m, 1H), 1.74 (d, J=12.4 Hz, 2H), 1.64 (q, J=4.0 Hz, 2H), 1.49 (td, J=12.6, 4.1 Hz, 2H), 1.42 (s, 9H), 1.29 (q, J=4.2 Hz, 2H). LCMS-A: rt 7.083 min; m/z 619 [M−H]−.

後処理
