Reaction Steps

Potassium phthalimide 2 (2.7 g, 14.6 mmol) was added to a solution of bromoethanol 1 in N,N-dimethylformamide (12 mL, 14.1 mmol). After stirring for 12 h at 70° C., the mixture was concentrated and then diluted with dichloromethane (100 mL). After removal of solids by filtration, the organic layer was washed with water, dried, and concentrated. The concentrate was purified by flash column chromatography (3:2 to 2:3 hexane-ethyl acetate) to give compound 3 as a white solid (1.19 g, 44.12%) having an RF of 0.22 (3:2 hexane-ethyl acetate). See FIG. 5.
