実験手順

A solution of 2-propenenitrile (0.043 mL, 0.00065 mol), bis(triphenylphosphine)palladium(II) chloride (0.0091 g, 0.000013 mol), 4-(4-bromo-3-methyl-1H-pyrazol-1-yl)-1H-pyrrolo[2,3-b]pyridine (0.036 g, 0.00013 mol), and tetraethylamine (TEA) (0.15 mL, 0.0011 mol) in DMF (0.15 mL, 0.0019 mol) was microwaved at 120° C. for 2 h. The solution was then diluted with ethyl acetate and washed with water (×2) and brine successively. The organic phase was dried and concentrated in vacuo to give 62 mg of the product as an orange solid. The orange solid was purified by prep-LCMS to give 12 mg of an off-white solid as a trifluoroacetic acid (TFA) salt which was triturated with MTBE (1 mL) to provide the purified product as a pale green solid. (dried at 60° C. for 4 h, 9 mg , 28% yield).
