실험 절차
To a stirred solution of 51.2 g (146.8 mmol) 6,8-dibromo-3-iodoimidazo[1,2-b]pyridazine which was prepared according to intermediate example 96c in NMP (450 mL) are added 12.35 g (176.2 mmol) sodium methanethiolate in one portion at 0° C. After reaction for 15 min, 700 mL water are added and the precipitate is filtered off and dried. Trituration with ether, filtration and drying in vaccuo. yields 44.3 g (65%) of the title compound
