6-CHLORO-5-METHYLPYRIDINE-3-BORONIC ACID Use and Manufacturing
General procedure: To a stirred solution of 5-bromotetrandrine (70 mg, 0.100 mmol) in the mixture of tolueneor dimethyl formamide (DMF) or 1, 4-dioxane and water (25 ml, 5:1, v/v) was addedsodium carbonate (aq, 5 ml, 1 M) and the resulting mixture was degassed ultrasonicallyat room temperature for 20 min. Tetrabutylammonium bromide (Tbab) (64.4 mg, 0.200 mmol), a boronic acid derivative (0.200 mmol) and pd(pph3)4 (34.6 mg, 0.030 mmol) were successively added to the mixture under a nitrogen or carbon dioxide atmosphere.The mixture was then heated to reflux for 24 h before being quenched with ice water (5 ml).The reaction mixture was extracted with ethyl acetate (2 × 15 ml). The combined organicextracts were washed with saturated sodium chloride solution (3 × 30 ml), and dried overanhydrous sodium sulfate. Removal of solvent followed by purification by preparative thinlayer chromatography (eluent: dichloromethane-methanol-ethyl acetate-petroleum ether, 15:1:1:1, v/v/v/v) afforded the final products Y1~Y15.DMF was dried over molecular sieves and purged with argon. Then N-(4-bromo-3- {[(dimethylamino)methylidene]sulfamoyl}phenyl)-2-(2-chlorophenyl)acetamide hydrochloride (1:1) (300 mg, 606 pmol), To a suspension of To a solution of 1-iodo-4-(trifluoromethoxy)benzene (288 mg, 1.0 mmol) and
