실험 절차

To 3-bromo-1-(4-(trifluoromethoxy)phenyl)-1H-1,2,4-triazole (C1) (0.50 g, 1.6 mmol), 2-(3-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)propyl)isoindoline-1,3-dione (C58) (0.64 g, 1.6 mmol), sodium bicarbonate (0.27 g, 3.3 mmol), and tetrakis(triphenylphosphine)palladium(0) (0.19 g, 0.16 mmol) in a 10-20 mL microwave vial equipped with a stir bar was added dioxane (12 mL) and water (4.1 mL). The reaction was capped and heated at 140° C. for 30 minutes in a Biotage Initiator® microwave reactor with external IR-sensor temperature monitoring from the side of the vessel. The mixture was diluted with ethyl acetate and washed with water. The aqueous layer was extracted with ethyl acetate. The combined organic layers were washed with brine, dried over sodium sulfate, filtered, and concentrated. Purification by flash column chromatography using 0-30% ethyl acetate/B, where B=1:1 dichloromethane/hexanes, as eluent provided a solid which was dried under house vacuum overnight. The title compound was obtained as a white solid (0.42 g, 53%): mp 145-148° C.; 1H NMR (400 MHz, CDCl3) δ 8.54 (d, J=0.8 Hz, 1H), 8.08 (d, J=8.1 Hz, 2H), 7.84 (ddd, J=5.5, 3.0, 0.8 Hz, 2H), 7.82-7.77 (m, 2H), 7.69 (ddd, J=5.5, 3.0, 0.8 Hz, 2H), 7.38 (dt, J=9.0, 1.0 Hz, 2H), 7.31 (d, J=8.0 Hz, 2H), 3.78 (t, J=7.2 Hz, 2H), 2.79-2.71 (m, 2H), 2.08 (p, J=7.5 Hz, 2H); 19F NMR (376 MHz, CDCl3) δ −58.03; ESIMS m/z 493 ([M+H]+).
