Procedure

A solution of potassium phthalimide (627 mg, 3.38 mmol) and 7-bromohept-1-ene in dry DMF (10 mL) was stirred at 100° C. under nitrogen for 1 h. Then, the reaction mixture was successively cooled to room temperature, filtered, diluted with ether, and filtered again. The filtrate was concentrated under reduced pressure to give the target product 75 as an oil, which was used without further purifications in the next step: m/z=244 (M+H)+.
