Versuchsvorschrift

7-bromo-2-isoquinolin-3-yl-6-methyl-chromen-4-one oxime was prepared using the method D, (step 2) illustrated in example 1C. 7-bromo-2-isoquinolin-3-yl-6-methyl-chromen-4-one O-tert-butyl oxime (100 mg, 0.22 mmol) was treated with a 1M solution of titanium tetrachloride (0.68 ml, 0.68 mmol) in dichloromethane (4 ml) to yield 7-bromo-2-isoquinolin-3-yl-6-methyl-chromen-4-one oxime (79 mg, 94%) as a yellow solid after recrystallization in hot chloroform. The compound was isolated as a 88/12 mixture of Z/E oxime isomers.
