実験手順

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 (132 mg, 0.340 mmol), 5-methyl-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-pyrazole (141 mg, 0.68 mmol), Pd(PPh3)4 (98 mg, 0.085 mmol) and 1.5N Na2CO3 (1.81 mL, 2.72 mmol) in dioxane (5.4 mL). The crude product is purified by silica gel column chromatography eluting with 95:5 DCM:NH3 (7M in MeOH) followed by trituration with diethyl ether and petroleum ether to afford the title compound (9 mg, 7%) as a pale green solid. 1H-NMR (400 MHz, d6-DMSO) δ (ppm) 2.27 (3H, s), 2.38-2.49 (7H, m), 3.14 (4H, m), 6.97 (2H, d), 7.70 (1H, s), 7.88 (2H, d), 7.99 and 8.43 (1H, br s), 8.68 (1H, s), 9.71 (1H, s), 12.92 and 12.98 (1H, br s).
