2,3-Dihydro-1,4-dioxino[2,3-b]pyridine Use and Manufacturing
a-1) Preparation of 2, 3-dihydro-[1, 4]dioxino[2, 3-b]pyridine2, 3-Dihydroxypyridine (2.22 g, 20.0 mmol) was dissolved in N, N'-dimethylformamide (100 mL), and added potassium carbonate (5.52 g, 40.0 mmol) at room temperature. 5 minutes after, 1, 2-dibromoethane (2.6 mL, 30.0 mmol) was added at the same temperature, and stirred at 90° C. overnight. The reaction solution was reverted to room temperature, filtered, and the obtained filtrate was concentrated in vacuo. Then, the obtained residue was added ethyl acetate. The suspension was filtered, washed ethyl acetate, and concentrated in vacuo. The title compound (157 mg (yield 5.7percent)) was obtained as a colorless oil.A solution of 2, 3-dihydroxy pyridine (10.0 g, 0.09 mole) in acetonitrile (200 mL) under N
