実験手順: A mixture of 1,5-dibromohexane (21.6 g, 0.09 mole) in acetone (75 ml) containing potassium phthalimide (12.3 g, 0.066 mole) was heated at reflux for 24 hr. The mixture was cooled, filtered and concentrated. The excess dibromide was recovered (6.3 g) via distillation at 1.5 mm, 130° internal temperature, and recycled. The total yield of crude product was 20.6 g (74%), mp 48°-51°. This material was used as such in the next step. was heated at reflux for 24 hr The mixture was cooled filtered concentrated The excess dibromide was recovered (6.3 g) via distillation at 1.5 mm, 130° internal temperature
