実験手順

A solution of methyl 2-(2-ethynylphenyl)acetate (K1) (0.129 g, 0.741 mmol) in DMF (3 mL) and Et3N (344 μL, 2.47 mmol) was added to a mixture of tert-butyl 4-(4-((4-chloro-5-(trifluoromethyl)pyrimidin-2-yl)amino)benzoyl)piperazine-1-carboxylate (A22) (0.300 g, 0.617 mmol), PdCl2 (PPh3)2 (0.065 g, 0.093 mmol), CuI (0.018 g, 0.093 mmol) and PPh3 (0.016 g, 0.062 mmol) in DMF (3 mL). The resulting mixture was heated under microwave irradiation at 120° C. for 15 minutes, diluted with EtOAc and passed through a plug of Celite, washing with EtOAc (60 mL). The filtrates were combined and the volatiles were removed in vacuo to give a residue that was purified by silica gel column chromatography (Biotage Isolera, 25 g SiO2 cartridge, 0-80% EtOAc in petroleum benzine 40-60° C.) to give the title compound A23 as a yellow oil (0.337 g, 88%); 1H NMR (400 MHz, CDCl3) δ 8.67 (s, 1H), 7.73 (d, J=8.6 Hz, 2H), 7.68 (dd, J=7.7, 1.0 Hz, 1H), 7.61 (s, 1H), 7.48-7.41 (m, 3H), 7.40-7.31 (m, 2H), 3.96 (s, 2H), 3.71 (s, 3H), 3.67-3.37 (m, 8H), 1.47 (s, 9H). LCMS-A: rt 6.393 min; m/z 624.1 [M+H]+.
