Procedure
2-isoquinolin-3-yl-7-(4-methoxyphenyl)ethynyl-chromen-4-one oxime was prepared in 9% overall yield using the method described in example 24, starting from 7-bromo-2-isoquinolin-3-yl-chromen-4-one O-tert-butyl oxime (example 2B) and 4-methoxyphenylacetylene. The title compound was purified by preparative HPLC (gradient 35-20% Water/acetonitrile+0.05% trifluoroacetic acid) and isolated as a yellow solid and as a 95/05 mixture of Z/E oxime isomers.
