Reaction Steps
This compound was prepared according to the procedure used to prepare 1,3-dihydro-1,3-dioxo-2H-isoindoleoctanoic acid ethyl ester. Thus, a mixture of 62.3 g (0.265 mole) of 6-bromohexanoic acid ethyl ester (ethyl 6-bromocapronate, 95%, Fluka) and 52.4 g (0.277 mole) of potassium phthalimide (98%, Aldrich) in 200 mL of dimethylformamide gave 67 g (87%) of crude title compound as a viscous oil. A 2.0 g sample of this oil was purified by high-pressure liquid chromatography (Waters Associates Prep LC/System 500A; PrepPak® 500 silica; ethyl acetate-hexanes, 1:10; flow rate 200 mL/min). Fractions containing title compound were combined and the solvents evaporated under reduced pressure to give 1.9 g (95% recovery) of colorless liquid.
