Dimethylformamide → HCID 86657560, compound

Participants

Reaction Steps

To a dimethylformamide (8.0 mL) solution of 3-hydroxy-benzoic acid methyl ester (928 mg, 6.1 mmol) was added potassium t-butoxide (750 mg, 6.7 mmol). Upon stirring the reaction at room temperature for 15 min, 3,6-dichloro-pyridazine (1.0 g, 6.7 mmol) was added. The reaction was stirred at room temperature for 15 h. Crude reaction mass was added to water, aqueous layer was acidified to pH 4.0 and product was extracted with ethyl acetate to give 3-(6-chloro-pyridazin-3-yloxy)-benzoic acid methyl ester (950 mg).
