YieldReaction ConditionsOperation in experiment
71% With palladium diacetate; sodium carbonate; triphenylphosphine; In ethanol; water; at 100℃;Inert atmosphere; General procedure: A solution of Pd(OAc)2 (0.03 eq) and triphenylphosphine (0.15 eq) in absolute ethanol (6 mL for 3 mmol of sulfonamide precursor) and anhydrous toluene (6 mL) was stirred at RT under nitrogen for 10 min. After that period, previously synthesized sulfonamide derivatives 13b-d, 6 mL of 2M aqueous Na2CO3, and commercially available 4-methyl-3-nitrobenzeneboronic acid (1.6 eq) were sequentially added. The resulting mixture was heated at 100 C in a sealed vial under nitrogen overnight. After being cooled to RT, the mixture was diluted with water and extracted with EtOAc. The combined organic phase were dried and concentrated. The crude product was purified by flash chromatography over silica gel column using n-Hex/EtOAc mixture as the eluent.
