Reaction Steps

32.3 g (271 mmol) 3-bromopropine are dissolved in 150 ml DMF and 50.3 g (271 mmol) phthalimide potassium salt are added under ice cooling. The suspension is warmed at 70° C. for eight hours. The mixture is concentrated under a vacuum and the residue is distributed between acetic acid ethyl ester and water. The organic phase is dried over sodium sulfate and the solvent is removed under vacuum. The residue is crystallized from acetic acid ethyl ester: Yield 36.4 g (72%) colorless crystals.
