反应详情

This compound may be prepared using methods as described for Compound 6, step 4 using (5-bromo-[1,2,4]triazolo[1,5-a]pyrazin-8-yl)-(4-morpholin-4-yl-phenyl)-amine (0.2 g, 0.53 mmol), 4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-thiophene-2-carboxylic acid amide (0.27 mg, 1.06 mmol), and Pd(PPh3)4 (0.15 mg, 0.133 mmol) in 1.5M Na2CO3 (aq) (2.84 mL, 4.26 mmol) and dioxane (10 mL). The reaction mixture is partitioned between water and ethyl acetate. A precipitate is formed, collected by filtration and purified by silica gel column chromatography using 95:5 DCM:MeOH to give the title compound (84.1 mg, 37.4%). 1H-NMR (400 MHz, d6-DMSO) δ (ppm) 3.13 (4H, m), 3.79 (4H, m), 7.01 (2H, d), 7.60 (1H, br s), 7.91 (2H, d), 8.10 (2H, s), 8.48 (1H, s), 8.66 (1H, s), 8.79 (1H, s), 9.96 (1H, s). LCMS: Rt 2.61 min (97.1%), m/z (APCI) 422 (M+H)+.
