YieldReaction ConditionsOperation in experiment
78% With (1,1'-bis(diphenylphosphino)ferrocene)palladium(II) dichloride; sodium carbonate; In 1,4-dioxane; water; at 90.0℃; for 6.0h;Inert atmosphere; A mixture of compound 3 (4mmol), <strong>[710348-41-7](3-(ethylsulfonamido)phenyl)boronic acid</strong> (4.8mmol), [1,1?-Bis(diphenylphosphino)ferrocene]dichloropalladium(II) (5mol %), and sodium carbonate (12mmol) in 1,4-dioxane (10mL) and water (5mL) was heated under nitrogen conditions (90C, 6h). After cooling to ambient temperature, the reaction mixture was filtered and concentrated. The residue was partitioned between water and dichloromethane. The organic layer was separated and purified by flash chromatography to get compound 3b (78%). (0029) 3b: Light yellow powder, 78% yield. 1H NMR (400MHz, Chloroform-d, delta ppm) 9.01 (d, J=1.7Hz, 1H), 8.72 (d, J=1.7Hz, 1H), 7.57-7.50 (m, 2H), 7.44-7.39 (m, 1H), 7.35-7.30 (m, 1H), 6.94 (s, 1H), 3.22 (q, J=7.4Hz, 2H), 2.74 (s, 3H), 1.43 (t, J=7.4Hz, 3H). ESI-HRMS m/z: 362.0923, [M+1] +, calcd for C15H15N5O4S: 361.0845.
