Procedure

This compound may be prepared using methods as described for Compound 6, step 4, using 5-bromo-N-(6-(4-isopropylpiperazin-1-yl)pyridin-3-yl)-[1,2,4]triazolo[1,5-a]pyrazin-8-amine (50 mg, 0.12 mmol), 5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-2,3-dihydro-isoindol-1-one (56 mg, 0.216 mmol) and Pd(PPh3)4 (35 mg, 0.03 mmol) in 1.5M Na2CO3 (0.64 mL) and dioxane (2 mL). The crude product is purified by silica gel column chromatography eluting with 95:5 DCM:MeOH followed by 90:10 DCM:MeOH. The title compound is obtained after trituration with a 10:1 mixture n-hexane:DCM (19 mg, 34%). Conversion into the mesylate salt, using 0.1M methanesulfonic acid (0.35 mL), gives the title compound as a yellow solid (20 mg, 69%).
