Reaction Steps

A mixture of tert-butyl-N-[1-[[5-(3,5-dimethylpyridin-4-yl)-6-ethynylpyridin-2-yl]amino]-1-oxopropan-2-yl]-N-methylcarbamate (E1a desilylated according to the general method exemplified for F1a) (50 mg, 0.12 mmol), 6-iodoquinoline (89 mg, 0.35 mmol), copper(I) iodide (2.2 mg, 0.01 mmol), Dichlorobis(triphenylphosphine)palladium(II) (8.1 mg, 0.01 mmol) and triethylamine (64 μl, 0.47 mmol) is stirred under argon atmosphere in NMP (0.5 ml) for 1 h at 50° C. The mixture is concentrated in vacuo and the product purified by RP HPLC. Yield: 28 mg (45%). HPLC-MS: M+H=536; tR=1.79 min (*Method—3).
