Procedure

2-isoquinolin-3-yl-6-[2-(4-methyl-piperazin-1-yl)-ethoxy]-chromen-4-one oxime was prepared in 49% overall yield using the method described in examples 44 and 44A, starting from 6-hydroxy-2-isoquinolin-3-yl-chromen-4-one O-tert-butyl oxime (example 41A) and 2-(4-methyl-piperazin-1-yl)-ethanol. The title compound was isolated as a yellow solid and as a 90/10 mixture of Z/E oxime isomers.
