Versuchsvorschrift

To a solution of 2,3,4,5-tetrahydro-1H-1-benzazepine (1.05 g, 7.14 mmol) in dichloromethans (40 ml) were added 4-cyanobenzoic acid (1.26 g, 8.57 mmol), triethylamine (1.00 g, 7.14 mmol), 4-(dimethylamino)pyridine (0.87 g, 7.14 mmol) and WSCDI (2.86 g, 14.28 mmol). The mixture was stirred at reflux for 18 h, cooled and evaporated in vacuo. The residue was partitioned between EtOAc and 1M KHSO4. The organic layer was washed with saturated sodium bicarbonate solution and brine, dried over MgSO4, and concentrated in vacuo to give a white solid; yield 1.50 g (76%).
