Utilizing the general procedure outlined in the synthesis of 2-[4-(6-bromopyridin-2-yl)-3-methoxyphenyl]-1,3-benzoxazole, 2-[3-methoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-1,3-benzoxazole (200 mg, 0.57 mmol) was reacted with 2-bromo-6-methylpyridine (65 μL, 0.57 mmol) to afford the desired 2-[3-methoxy-4-(6-methylpyridin-2-yl)phenyl]-1,3-benzoxazole as a colorless solid: 1H NMR (CDCl3, 300 MHz) δ 7.96–7.95 (m, 2H), 7.89 (s, 1H), 7.82–7.79 (m, 1H), 7.67–7.60 (m, 3H), 7.39–7.36 (m, 2H), 7.14–7.12 (m, 1H), 4.00 (s, 3H), 2.65 (s, 3H). MS (ESI) 317 (M+H)+.
