Reaction Steps

To a mixture of 4-(4-ethylbenzyl)-3-methoxy-pyridazine (2.11 g, 9.24 mmol) and chloroform (20 ml), trimethylsilyliodo (1.45 ml, 10.2 mmol) was added and this reaction mixture was stirred at 60° C. for 25 hours. After cooling to room temperature, the reaction mixture was diluted with methanol and concentrated. The resulting residue was purified by silica gel column chromatography (chloroform:methanol=20:1) to give the titled compound (1.36 g, 69%) as a yellow powder.
