実験手順
The compound (S)-5-bromo-3-(1-(2,6-dichloro-3-fluorophenyl)ethoxy)-2-aminopyridine (12.58 g, 33.11 mmol) was dispersed in toluene (100 mL), and triethylamine (14.05 g, 139.06 mmol) and copper iodide (126 mg, 0.66 mmol) were added successively. Under the protection of N2 atmosphere, PdCl2(PPh3)2 (465 mg, 0.66 mmol) was added. The reaction mixture was heated to 30° C., stirred for 0.5 h. Ethynyltrimethylsilane (9.11 g, 92.71 mmol) was added dropwise, gradually warmed to 90° C., and stirred overnight. Through HPLC test, it was found that the raw materials were completely reacted. The reaction liquid was cooled down, washed with water, and the toluene layers were combined. The toluene layer was dried over anhydrous Na2SO4, concentrated; the residue was purified via silica gel column chromatography (petroleum ether:ethyl acetate=3:1) to yield the target product as yellow solid (10.6 g, yield: 80%).
