Reaction Steps
To a solution of compound NaH (248 mg, 10.2 mmol) in DMF (10 mL) was added quinolin-8-ol (500 mg, 3.44 mmol) at 28° C. After stirring for 5 minutes, ethyl 2-bromo-2-methylpropanoate (806 mg, 4.13 mmol) was added and the reaction mixture was stirred for an additional 16 h at 28° C. until the reaction was complete by TLC. The mixture was then diluted with water (50 mL) and extracted with ethyl acetate (3×20 mL). The combined organic layers were washed with brine (30 mL), dried over Na2SO4 and concentrated to give the crude product (400 mg, 44.8%) as colorless oil which was used in next step without further purification.
