实验步骤: Triphenylphosphine was added portionwise to a solution of 4-bromo-2-fluorobenzenesulfonyl chloride (8.44 g) in THF (30 ml) at 0° C. After 15 min water was added and the colourless solution was stirred at 20° C. for 18 h. The solvent was removed in vacuo, the residues dissolved in DCM and extracted with 2M sodium hydroxide (twice). The aqueous layers were washed with DCM, combined, acidified (4M HCl) and extracted with ethyl acetate (thrice). These organic extracts were dried (MgSO4) and evaporated to give the sub-title compound (5.89 g). The solvent was removed in vacuo the residues dissolved in DCM extracted with 2M sodium hydroxide (twice) The aqueous layers were washed with DCM extracted with ethyl acetate (thrice) These organic extracts were dried (MgSO4) evaporated

实验步骤: A mixture of 2-fluoro-4-bromothiophenol (300 mg), 2,6-dichloro-pyridazine (149 mg), potassium carbonate (400 mg) and acetone (6 mL) was prepared and refluxed for two hours. The acetone from the mixture was evaporated and the resulting residue was dissolved in a solution of methanol (3 mL) and sodium metal (166 mg). The resulting solution was refluxed for 1 hour. Evaporation of methanol afforded 3-(4-bromo-2-fluoro-phenylsulfanyl)-6-methoxy-pyridazine, which was not isolated but was immediately used in Step 2. was prepared refluxed for two hours The acetone from the mixture was evaporated the resulting residue was dissolved in a solution of methanol (3 mL) and sodium metal (166 mg) The resulting solution was refluxed for 1 hour Evaporation of methanol
