Versuchsvorschrift

To 300 mg (1.389 mmol) of the 3-bromo-6-fluoroimidazo[1,2-b]pyridazine, was added N1-methyl-N1-phenylpropane-1,3-diamine (456 mg, 2.778 mmol) Cs2CO3 (903 mg, 2.778 mmol) and 10 mL DMF. This mixture is stirred overnight at rt. It was diluted with 30 mL EtOAc, and 15 mL of water. The organic layer was washed with brine and dried over MgSO4. It was concentrated and purified using silica gel chromatography (ISCO) eluting with 0-10% MeOH/DCM to obtain 301 mg (60%) of product.
