Reaction Steps
To a solution of 1-(pyridazin-3-yl)ethanol (3) (50 mg, 0.40 mmol) in DCM (1 mL), there was added sulfurous dichloride (0.2 mL). The resulting solution was stirred at room temperature for 3 hrs. Solvent was removed to give 3-(1-chloroethyl)pyridazine (4), which was used for the next step without purification.
