Versuchsvorschrift

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)-(2-fluoro-4-morpholin-4-yl-phenyl)-amine (80 mg, 0.203 mmol), 4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-pyrazole (79 mg, 0.406 mmol), and Pd(PPh3)4 (59 mg, 0.051 mmol) in 1.5N Na2CO3 (1.09 mL, 1.62 mmol) and dioxane (3.25 mL). The reaction mixture is purified by silica gel column chromatography eluting with 97:3 DCM:NH3 (7M in MeOH). The fractions containing the product are combined and evaporated in vacuo to afford a solid which is triturated with diethyl ether and petroleum ether to yield the title compound (29 mg, 38%). LCMS: Rt 2.90 min (96%).
