2,3-Dimethoxypyridine Use and Manufacturing

A three-necked flask was charged with Compound 1 (5.58 g, 39.0 mmol), N, N-dimethylformamide (60 mL) and sodium methoxide (6.20 g, 115.0 mmol); the reaction was stirred overnight at 60 ° C.The reaction was cooled to room temperature, water (120 mL) was added and extracted with ethyl acetate (80 mL x 3); the organic phases were combined, washed with water (100 mL x 2) and saturated brine (100 mL), dried over sodium sulfate, . The filtrate was spin-dried to give a yellow liquid, compound 2 (4.0 g, 28.9 mmol, 74percent).
