실험 절차

Following the procedure of Example 1b), except substituting the compound from Example 2b) for 5-bromo-2-nitrophenol and substituting 3-carboxyphenylboronic acid for 4-carboxyphenylboronic acid, the title compound was prepared (2.13 g; 47%) as a tan powder. 1H NMR (300 MHz, d6-DMSO) δ 8.12 (s, 1H), 8.03 (d, J=7.9 Hz, 1H), 7.94 (dd, J=7.9 Hz, 1.5 Hz, 1H), 7.85 (d, J=7.9 Hz, 1H), 7.76 (dd, J=7.5, 1.5 Hz, 1H), 7.66 (t, J=7.5 Hz, 1H), 7.46 (t, j=7.9 Hz, 1H), 3.46 (s, 3H).
