Reaction Steps

5-Bromo-3,3-dimethyl-2,3-dihydroisoindol-1-one is converted to the corresponding boronate in a fashion analogous to Intermediate 6, Step 3. This is then used to prepare the title compound from (5-bromo[1,2,4]triazolo[1,5-a]pyrazin-8-yl)-[4-(4-isopropylpiperazin-1-yl)-phenyl]amine using methods as described for Compound 120, Step 4. LCMS: Rt=0.92 (100%), m/z=497 (M+H)+.
