실험 절차

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 (80 mg, 0.206 mmol), 2-methoxypyridine-4-boronic acid (63 mg, 0.412 mmol), Pd(PPh3)4 (0.052 mmol) and 1.5N Na2CO3 (1.1 mL, 1.65 mmol) in 2:1 DMF/dioxane (2.2 mL). The crude product is purified by silica gel column chromatography using 96:4 DCM:NH3 (7M in MeOH) and the fractions containing the desired product are combined and evaporated to afford the title compound (40 mg, 47%). HPLC (254 nm): Rt 2.26 min (65%).
