Reaction Steps

A mixture of the white crystal of 5-Bromo-N-(3,5-dichlorophenyl)-2-methoxybenzenesulfonamide (206 mg, 0.5 mmol), lithium iodide (134 mg, 1 mmol) and 2,4,6-collidine (5 mL) was refluxed for 30 minutes under argon atmosphere. After cooling to room temperature, the reaction mixture was poured into 2N hydrochloric acid and extracted with ethyl acetate. After the ethyl acetate layer was washed successively with water and brine, dried over anhydrous magnesium sulfate, the solvent was evaporated under reduced pressure. The obtained residue was crystallized from n-hexane-ethyl acetate to give the title compound (90 mg, 45.3%) as a white crystal.
