YieldReaction ConditionsOperation in experiment
75% LiOH.H20 (180 mg,4.24 mmol) was added to a solution of 2-bromo-6-chlorobenzoic acid (i-la) (1.0 g, 4.24mmol) in THF (30 ml). The mixture was stirred at 25 C for lh. Then the Me2SO4 (1.1 g, 8.48mmol) was added to the reaction mixture. The mixture was warmed to 85 C and stirred at 85C for 21 h. After cooling, NH3.H20 was added dropwise to the mixture until pH=7-8. Thesolution was poured into water and THF was evaporated. The water layer was extracted withEA (60 ml). The organic layer was dried over Na2SO4 and concentrated to obtain 800 mg(75%) of the title compound. LCMS (ESI): calc?d for C8H6BrC1O2 [M+H]: 251, found: 251.

YieldReaction ConditionsOperation in experiment
70% With bis-triphenylphosphine-palladium(II) chloride; 1,1,3,3-Tetramethyldisiloxane; tetrabutylammomium bromide; In 1,4-dioxane; at 120℃; for 18h;Inert atmosphere; Combine mg (0.5 mmol) of 3,4-dimethoxy iodobenzene, 550.3 mg (5 mmol) of dimethyl sulfite, 35.1 mg (0.05 mmol) of bistriphenylphosphorus palladium dichloride (II), 100.7 mg (0.75 mmol) of 1,1,3,3-tetramethyldisiloxane, and 161.3 mg (0.5 mmol) of tetrabutylammonium bromide were added to the reaction tube,heated at120oC for 18 hours, After the reaction, it was cooled, filtered, and the filtrate was rotary evaporated to remove the solvent. The residue was chromatographed on silica gel column, washed with petroleum ether, and detected by TLC. The effluent containing the product was combined, the solvent was distilled off by a rotary evaporator, and the solvent was removed by vacuum drying to obtain a white solid 75.7. Milligrams of 1,2-dimethoxy-4-(methylsulfonyl)benzenebenzene, the yield is 70%.
