実験手順
0.86 g of N-(6-Chloroimidazo[1,2-b]pyridazine-2-carbonyl)glycine ethyl ester was suspended in 30 ml of ethyl acetate; 1.2 g of N-chlorosuccinimide was added, followed by thermal refluxing for 20 hours. After cooling, 30 ml of tetrahydrofuran was added; the mixture was washed with an aqueous solution of sodium thiosulfate and saline, dried over magnesium sulfate and concentrated under reduced pressure; ethyl ether was added to the residue; the crystal precipitated was collected by filtration, washed with ethyl ether and dried to yield 0.552 g of the title compound.
