실험 절차

A solution of 7-bromo-2-isoquinolin-3-yl-chromen-4-one oxime (52 mg, 0.142 mmol), trans-dichlorobis(triphenylphosphine)palladium (10 mg, 0.014 mmol), copper iodide (5.3 mg, 0.028 mmol) in dimethylformamide (3 ml) was degassed with argon for 10 min and then treated with triethylamine (30 μl, 0.213 mmol) and phenyl acetylene (19 μl, 0.170 mmol). The solution was warmed to 90° C. for 18 hours and then poured onto a 0.5N aqueous solution of hydrogen chloride, extracted with ethyl acetate and purified by preparative HPLC (gradient 25-10% Water/acetonitrile+0.05% trifluoroacetic acid) to yield 2-isoquinolin-3-yl-7-phenylethynyl-chromen-4-one oxime (7.3 mg, 13%) as a yellow solid and a 80/20 mixture of Z/E oxime isomers.
