63 ml of a 32% sodium methoxide solution in methanol are added to a solution of 57 g 3-Chloro-6-pyridin-4-yl-pyridazine in methanol, and the reaction mixture is stirred under reflux for 1.5 h. The solvent is removed under reduced pressure, the residue suspended in 0.7 L water and the pH adjusted to 7. Extraction with dichloromethane yielded 57 g 3-Methoxy-6-pyridin-4-yl-pyridazine, which is used without further purification.
