実験手順

A mixture of 3-(6-chloroimidazo[1,2-b]pyridazin-2-yl)benzonitrile (1 mmol) and Pd/C (20 mg) in DMF/THF (10 ml/10 ml) was stirred at r.t. for 6 h equipped with a H2 balloon. Then the solvent was removed under reduced pressure and 3-(imidazo[1,2-b]pyridazin-2-yl)benzonitrile was obtained with a yield of 88.5%.
