Reaction Steps

A 1.0M tetrahydrofuran solution of lithium aluminum hydride (9.8 ml) was introduced under a nitrogen atmosphere to a dry 100 ml three-necked roundbottom flask using a syringe. Concentrated sulphuric acid (0.264 ml) was cautiously added under cooling on an ice bath, and the resulting solution was stirred at room temperature for 1.5 hour. The above amide was dissolved in dry tetrahydrofuran (9.8 ml) and slowly added. The reaction mixture was stirred overnight. The reaction was quenched by addition of water (0.4 ml), 4N sodium hydroxide (0.4 ml) and water (1.2 ml), successively. The resulting mixture was filtered (hyflo) and the filtercake was washed with diethyl ether and ethyl acetate. The solvent was evaporated affording 5-(3-chloropropyl)-6, 11-dihydro-5H-dibenzo[b,e]azepine, which was used for further reaction without purification.
