Reaction Steps

2.15 g of 5-nitro-2-[2-(3-benzyloxyphenyl)chroman-6-yloxy]pyridine was dissolved to 600 ml of ethanol and 430 mg g of 10% palladium on charcoal was added under inert atmosphere. Starting material was hydrogenated at room temperature to give quantitative yield of 3-[6-(5-aminopyridin-2-yloxy)chroman-2-yl]phenol 1H NMR (400 MHz, d6-DMSO) δ: 9.50 (bs, 1H), 7.52 (d, 1H, J 3.0 Hz), 7.17 (t, 1H, J 8.1 Hz), 7.05 (dd, 1H, J 3.0, 8.6 Hz), 6.84-6.68 (m, 7H), 5.01-4.99 (m, 3H), 2.91-2.86 (m, 1H), 2.70-2.63 (m, 1H), 2.14-2.08 (m, 1H), 1.96-1.89 (m, 1H).
