実験手順
14 g of 6-chloroimidazo[1,2-b]pyridazine (Example 1.0) were suspended in 364 ml of acetonitrile, and 20.51 g of N-iodosuccinimide were added. The mixture was stirred at RT for 19 hours. A further 4.31 g of N-iodosuccinimide were added, and the mixture was stirred for 24 hours. The reaction was cooled and the precipitated solid was filtered off with suction, washed with acetonitrile and dried. 17.67 g of the desired product are obtained.
