Reaction Steps
The title compound was synthesized in analogy to example 66, from (4,4-difluoro-piperidin-1-yl)-[5-(4-isopropyl-piperazine-1-carbonyl)-1H-indol-2-yl]-methanone (example 32), cyclobutylboronic acid (commercially available), copper(II) acetate and pyridine using chloroform as solvent and stirring under reflux for 6 days, to give the desired product as a light brown foam (14%).
