実験手順
6-(5-Nitropyridin-2-yloxy)-2-phenylchromen-4-one was prepared as described for 5-nitro-2-(2-phenylchroman-6-yloxy)pyridine in Example 1(b) starting from 500 mg of 6-hydroxyflavone. The product was recrystallised from a mixture of 2-propanol and acetone. 1H NMR (300 MHz, d6-DMSO) δ: 9.04 (d, 1H, J 2.9 Hz), 8.67 (dd, 1H, J 9.0, 2.9 Hz), 8.16-8.13 (m, 2H), 7.95 (d, 1H, J 9.0 Hz), 7.82 (d, 1H, J 2.9 Hz), 7.63 (dd, 1H, J 9.1, 2.9 Hz), 7.64-7.61 (m, 3H), 7.38 (d, 1H, J 9.1 Hz), 7.09 (s, 1H).
