실험 절차

A 1.0 M solution of lithiumaluminium hydride in tetrahydrofuran (18.7 ml, 18.7 mmol) was introduced into a 250 ml dry, three-necked, roundbottom flask under a nitrogen atmosphere. The solution was cooled on an icebath. Concentrated sulphuric acid (0.5 ml) was added dropwise, with caution, over 10 minutes. More dry tetrahydrofuran (20 ml) was added to compensate for evaporated solvent and the mixture was stirred for 15 minutes. Additional tetrahydrofuran was added (20 ml) and the icebath was removed. The mixture was stirred for 75 minutes at room temperature. The above amide (3.0 g, 9.3 mmol) was dissolved in dry tetrahydrofuran (25 ml) and dropwise added over 20 minutes. The reaction mixture was stirred for 1 h. Water (0.7 ml) was added, followed subsequently by 4 N sodium hydroxide (0.7 ml) and water (2.1 ml). Stirring was continued for 30 minutes. The mixture was filtered (hyflo) and evaporated in vacuo, affording 2.70 g (95%) 3-chloro-5-(3-chloropropyl)-10,11-dihydro-5H-dibenz[b,f]azepine as an oil.
