Nitrogen → N-(3-(benzofuran-2-yl)-5-nitrophenyl)acetamide

Participants

Reaction Steps

A solution of N-(3-bromo-5-nitrophenyl)acetamide of Example 1(c) (2 g, 7.7 mmol) in 1,2-dimethoxyethane (25 ml) was degassed by N2 bubbling for 5 min. 2-(Benzofuran-2-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (2.45 g, 10 mmol, 1.3 eq.) was added and the mixture was degassed for another 5 min. Pd(dppf)Cl2 (0.63 g, 0.77 mmol, 0.1 eq.) and aqueous sodium carbonate (2.45 g, 23.1 mmol, 3.0 eq.) were added and the procedure of Example 1(d) was followed. The crude residue of the product was directly used for the next step.
