反応手順

3.0 g (13.3 mmol) of 6-(3,4,5-trifluorophenyl)-2H-pyridazin-3-one and 4.8 g (14.4 mmol) of caesium carbonate are suspended in 250 ml of DMF, 3.0 g (13.3 mmol) of 5-(bromomethyl)2,1,3-benzothiadiazole are added, and the mixture is stirred at room temperature. After 15 h, 110 ml of water are added to the reaction mixture, which is then stirred at room temperature for 2 h. The resultant precipitate is filtered off with suction and washed with water and dried in vacuo.
