Reaction Steps
In a 50 mL round-bottom flask fitted with magnetic stirrer were placed 3-hydroxypyridine-2-carboxylic acid methyl ester (3.5 g, 22.80 mmol), K2CO3 (3.46 g, 25.0 mmol), MeI (4.87 g, 34.3 mmol) and DMF (20 mL). The reaction mixture was stirred for 18 h at rt under nitrogen. The reaction mixture was diluted with EtOAc (30 mL) and water (10 mL). The organic layer was separated and aqueous layer was extracted with EtOAc. The combined organic extracts were dried over Na2SO4 and concentrated to give the crude product. The crude product was purified by column chromatography using 30% EtOAc in hexane to give 2.1 g of 3-methoxypyridine-2-carboxylic acid methyl ester (54%).
