Versuchsvorschrift
The mixture of [1-(3-pyridin-2-yl-imidazo[1,2-b]pyridazin-2-yl)-ethyl]-carbamic acid benzyl ester (600 mg, 1.6 mmol) and dimethylsulfide (1.2 mL) in TFA (7.5 mL)) was stirred at rt overnight. The mixture was concentrated in vacuo. The residue was dissolved in EtOAc. The organic layer was washed with satd. sodium bicarbonate solution, dried over sodium sulfate, filtered and concentrated in vacuo to provide 1-(3-pyridin-2-yl-imidazo[1,2-b]pyridazin-2-yl)-ethylamine (450 mg): LC-MS (ESI) m/z 240.0 [M+H]+.
