Reaction Steps

0.70 g (5.2 mmol) of sodium acetate is added to a solution of 1.02 g (4.70 mmol) of 1-(4-fluorophenyl)-2-pyridazin-4-ylethanone in 20 ml of acetic acid and then 0.26 ml (5.2 mmol) of bromine in solution in a few ml of acetic acid is added dropwise (slight exotherm). After 30 minutes at ambient temperature, the reaction medium is cooled and 60 ml of water are added. The product is extracted with diethyl ether. The cooled organic phase is washed with an aqueous solution of sodium hydrogen carbonate, dried over sodium sulfate and filtered.
