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-(4-methyl-piperazin-1-yl)-phenyl]-amine (100 mg, 0.258 mmol), 5-(4,4,5,5-tetramethyl-[1,3,2]dioxa-borolan-2-yl)-thiophene-2-carboxylic acid amide (130 mg, 0.516 mmol) and Pd(PPh3)4 (74 mg, 0.0645 mmol) in aqueous 1.5M Na2CO3 (1.37 mL, 2.06 mmol) and dioxane (2.75 mL). After evaporation of the solvent, the residue is purified by silica gel column chromatography eluting with 96:6 DCM:NH3 (7M in MeOH) to afford the title compound (23 mg, 21%). LCMS: Rt 1.94 min (97.9%). 1H-NMR (400 MHz, d6-DMSO) δ (ppm) 2.26 (3H, s), 2.49 (4H, m), 3.14 (4H, m), 6.98 (2H, d), 7.51 (1H, br s), 7.85-7.89 (2H, m), 8.03 (2H, d), 8.10 (1H, br s), 8.38 (1H, s), 8.82 (1H, s), 10.10 (1H, s). LCMS: Rt 1.94 min, (97.9%), m/z (APCI) 435 (M+H)+.
