Reaction Steps
To a solution of 2-hydroxy-4-methoxy-benzonitrile (9.637 g, 64.61 mmol) in ethanol (50 mL) were added potassium carbonate (17.88 g, 129.2 mmol) and iodoethane (15.7 mL, 193.8 mmol). The reaction mixture was heated at gentle reflux for 12 h. The solvent was removed to afford a yellow-brown paste. It was then taken in diethyl ether (50 mL) and water (20 mL). The layers were separated and the aqueous layer was extracted with diethyl ether (2×150 mL). The combined organic extracts were washed with water (1×20 mL), brine (1×20 mL), and dried over anhydrous sodium sulfate. The solids were then filtered off, and the filtrate was concentrated in vacuo. Purification of the crude residue by flash chromatography (Biotage system, KP-Sil™ 32–63 μm, 60 Å silica gel) eluting with 10–15% ethyl acetate in hexanes yielded 2-ethoxy-4-methoxy-benzonitrile as yellow solids (9.487 g, 83%).
