Reaction Steps

To a solution of 50 mg (121 μmol) N-cyclopropyl-4-{6-[(3-fluorophenyl) sulfanyl]-8-[(3,3,3-trifluoropropyl)amino]imidazo[1,2-b]pyridazin-3-yl}-2-methylbenzamide, which was prepared according to intermediate example 209 in 1.0 mL dichloromethane were added 0.71 mg methyl(trioxo)rhenium, 1.77 mg isonicotinonitrile and 58 μL aqueous hydrogen peroxide (30%). The mixture was stirred for two days at 23° C., poured into sodium thiosulfate solution and extracted with dichloromethane. The organic phase was dried over sodium sulfate. After filtration and removal of solvent the residue was purified by chromatography to give 14.9 mg (53%) of the title compound A and 4.5 mg (8%) of the title compound B.
