YieldReaction ConditionsOperation in experiment
3.7 g With (1,1'-bis(diphenylphosphino)ferrocene)palladium(II) dichloride; potassium acetate; In 1,4-dioxane; at 85.0℃;Inert atmosphere; General procedure: Step 34b: N-(3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)acetamide (Compound 0602-107)[0334]To a solution of compound 0601-107 (2.5 g, 11.6 mmol) and bis(pinacolato)diboron (4.4 g, 17.5 mmol) in dioxane (100 mL) was added potassium acetate (3.4 g, 35 mmol) and PdCl2(dppf)2 (0.95 g, 1.1 mmol). The mixture was degassed with nitrogen and heated at 85 C. for overnight. The reaction mixture was concentrated under reduced pressure to afford the crude product, which purified by column chromatography (ethyl acetate in petroleum ether, 15% v/v) to give the compound 0602-107 (1.55 g, 51%) as a pink solid. LCMS: 262 [M+1]+. 1H NMR (400 MHz, DMSO-d6) delta 1.29 (s, 12H), 2.03 (s, 3H), 7.30 (s, 1H), 7.31 (d, J=2.0 Hz 1H), 7.73 (d, J=2.0 Hz, 1H), 7.89 (d, J=1.6 Hz, 1H), 9.93 (s, 1H).
With palladium bis[bis(diphenylphosphino)ferrocene] dichloride; potassium acetate; In 1,4-dioxane; at 85.0℃;Inert atmosphere; General procedure: Compound in dioxane (100mL) 0601-107 (2.5g, 11.6mmol) and a solution of bis (pinacolato) diboron (4.4 g, 17.5 mmol), potassium acetate (3.4 g, 35 mmol) and and PdCl2 (dppf) 2 ( 0.95g, 1.1mmol) was added. The mixture was degassed with nitrogen and heated overnight at 85 C.. The reaction mixture was concentrated under reduced pressure to give the crude product, which was purified by column chromatography (petroleum ether in ethyl acetate, 15% v / v) to give the compound 0602-107 as a pink solid obtained (1.55 g, 51%).
