Reaction Steps
20 mL ACN are added to 0.50 g (1.11 mmol) 3-(4-chlorophenyl)-6-chloropyridazine and 3.33 g (22.2 mmol) NaI before 189 μl fuming conc. HCl are added and the mixture is stirred at 80° C. for 4 h. The mixture is alkalised with aq. ammonia solution (32%) diluted with water and extracted with EtOAc. The org. phases are combined, dried with Na2SO4 and the solvent is removed in vacuo. The resulting crude product is triturated with TBME.
