Procedure

2.9 (12.6 mmol) of 6-(2-amino-indan-5-yl)-4,5-dihydropyridazin-3(2H)-one are dissolved in a mixture of 30 ml of dioxan and 10 ml of acetone, and 1.42 g (14 mmol) of triethylamine and 2.8 g of p-fluorobenzenesulphonyl chloride are added. After 2 hours, the mixture is evaporated, water is added to the residue, and the reaction product is filtered off with suction and recrystallised from glacial acetic acid.
