(16b) 2-Methoxypyridin-4-ol A solution of 4-(benzyloxy)-2-methoxypyridine produced in Example (16a) (4.65 g, 21.6 mmol) and 10% palladium carbon (2.30 g, 2.16 mmol) in ethanol (100 mL) was stirred in a hydrogen atmosphere at room temperature for 30 minutes. The insoluble matter was separated by filtration and then the filtrate was concentrated to obtain the title compound (2.70 g, 99%) as a colorless oil. 1H-NMR (400 MHz, CDCl3): δ ppm: 3.90 (3H, s), 6.13 (1H, s), 6.42 (1H, d, J = 5.9 Hz), 7.80 (1H, brs).
