반응 단계

The title compound was prepared as described in Example 10 using 3-bromo-1-(4-(trifluoromethyl)phenyl)-1H-1,2,4-triazole (C1b), benzyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzylcarbamate (C13), tri-tert-butylphosphonium tetrafluoroborate, palladium(II) acetate, and cesium fluoride and isolated as a white solid (0.846 g, 36%): 1H NMR (400 MHz, DMSO-d6) δ 9.53 (s, 1H), 8.28-8.14 (m, 2H), 8.16-8.04 (m, 2H), 8.04-7.95 (m, 2H), 7.92 (t, J=6.2 Hz, 1H), 7.49-7.13 (m, 7H), 5.07 (s, 2H), 4.29 (d, J=6.2 Hz, 2H); 19F NMR (376 MHz, DMSO-d6) δ −60.79; ESIMS m/z 453 ([M+H]+).
