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 (80 mg, 0.21 mmol), 4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-furan-2-carboxylic acid amide (101 mg, 0.42 mmol), and Pd(PPh3)4 (62 mg, 0.053 mmol) in 1.5M Na2CO3 (aq) (1.143 mL, 1.71 mmol), and dioxane (4 mL). The crude product is purified by silica gel column chromatography eluting with DCM and 97:3 DCM:NH3 (7M in MeOH). The title compound is isolated after trituration with diethyl ether (35.4 mg, 42%). Conversion into the mesylate salt using 1M methanesulfonic acid in MeOH (0.0793 mL) affords the title compound as a solid (35 mg).
