Reaction Steps
A solution of ethyl 2-(4-bromobutyl)benzofuran-6-carboxylate (3.25 g., 0.01 mole) and potassium phthalimide (2.04 g., 0.011 mole) in dimethylformamide (25 ml.) is stirred at 25°-27° C. for 18 hours. The solution is poured into water. The precipitated ethyl 2-(4-phthalimidobutyl)benzofuran-6-carboxylate is collected by filtration.
