Reaction Steps

The title compound was synthesized in analogy to example 5, after stirring for 6.5 days at 35° C., from 1-{4-[5-(4-isopropyl-piperazine-1-carbonyl)-1H-indole-2-carbonyl]-piperazin-1-yl}-2-methyl-propan-1-one (example 31) and 2-chloropyridine-4-boronic acid to afford the desired product as light-brown foam (43%). MS (ISP): 565.4 (M+H)+.
