4-Bromo-3,6-dichloropyridazine Use and Manufacturing
Step 1: An oven-dried flask was equipped with a magnetic stir bar and charged with 4-bromo- 3, 6-dichloropyridazine (0.227 g, 1.0 mmol), [l, l'-bis(diphenylphosphino)ferrocene] (1181) dichloropalladium(II) (75.0 mg, 0.1 mmol), and 4 4, 4, 5, 5-tetramethyl-2-vinyl-l, 3, 2- dioxaborolane (0.l7lmL, 1.0 mmol). The flask was sealed with a rubber septum, and then evacuated and backfilled with argon (repeated a total of 3 X). Dioxane (6 mL) and 2N aq. K2CO3 (1.5 mL, 3.0 mmol) were added and the reaction was heated to 50 C for 3 h. The reaction was cooled to room temperature, diluted with water (2 mL) and extracted with EtOAc (3 X). The combined organic layers were dried over Na2S04, concentrated under reduced pressure, and purified by column chromatography, eluting with a EtO Ac/hexanes gradient (0-50% EtOAc) to provide 3, 6-dichloro-4-vinylpyridazine (0.145 g, 82%).
