A mixture of 4-chloro-5-fluoro-1-(triisopropylsilyl)-1H-pyrrolo[2,3-b]pyridine (250 mg), N-methylcyclohexanamine (306 μl), Pd(OAc)2(17 mg), sodium tert-butoxide (176 mg), 2-dicyclohexylphosphino-2′,4′,6′-tri-1-propyl-1,1′-biphenyl (73 mg) and 1,4-dioxane (2.5 mL) was evacuated and backfield with N2 three times, then degassed with N2 for 10 minutes. The mixture was heated at 100° C. for 2.5 hours. After cooling to ambient temperature, the reaction mixture was concentrated. Purification of the crude product by column chromatography (silica gel, n-hexane:EtOAc=1:50) afforded N-cyclohexyl-5-fluoro-N-methyl-1-(triisopropylsilyl)-1H-pyrrolo[2,3-b]pyridin-4-amine (53 mg) as a colorless solid.
