Reaction Steps

To a stirred mixture of 2-methylquinolin-7-ol (300 mg, 1.88 mmol), Cs2CO3 (1.84 g, 5.65 mmol) and NMP (10 mL) was added 1-bromo-2-methoxyethane (0.786 g, 5.65 mmol). The reaction mixture was stirred at ambient temperature overnight. The reaction was partitioned between ether and water. The aqueous layer was extracted with ether. The combined organic layers were washed with water and brine, dried and concentrated under reduced pressure. The residue was purified by flash chromatography on silica gel (2:1 to 1:2 hexanes/EtOAc) to give 7-(2-methoxyethoxy)-2-methylquinoline (235 mg, 57%).
