Participants

Reaction Steps

Amide coupling of benzofuran-2-carboxylic acid with 4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenylamine was done according to Example 20, Step 4 to give benzofuran-2-carboxylic acid [4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-amide in 83% yield. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.3 (s, 12 H) 7.4 (m, 1 H) 7.5 (m, 1 H) 7.7 (d, J=8.3 Hz, 2 H) 7.7 (dd, J=8.5, 0.9 Hz, 1 H) 7.8 (m, 4 H) 10.6 (s, 1 H)
