Reaction Steps

2-(3-Methyl-2-phenylchroman-6-yloxy)-5nitropyridine was prepared as described for 5-nitro-2-(2-phenylchroman-6-yloxy)pyridine in Example 1(b) starting from 600 mg of 3-methyl-2-phenylchroman-6-ol. The product was purified by column chromatography using heptane-2-propanol (20:1) as an eluant. 1H NMR (400 MHz, d6-DMSO) δ: 9.04 (d, 1H, J 2.8 Hz), 8.59 (dd, 1H, J 9.1, 2.8 Hz), 7.43-7.36 (m, 5H), 7.19 (d, 1H, J 9.1 Hz), 7.00 (d, 1H, J 2.6 Hz), 6.95 (dd, 1H, J 8.7, 2.6 Hz), 6.86 (d, 1H, J 8.7 Hz), 4.73 (d, 1H, J 9.3Hz), 2.85 (dd, 1H, J −16.7, 5.0 Hz), 2.64 (dd, 1H, J −16.5, 10.9 Hz), 2.18 (m, 1H), 0.77 (d, 3H, J 6.7 Hz).
