Procedure
3-Cyclobutyl-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ol (E3) (300 mg, 1.38 mmol) was dissolved in pyridine (10 ml), cooled in an ice bath and treated with sodium hydride (60% in mineral oil) (66 mg, 1.66 mmol) under argon. The resulting mixture was stirred for 5 minutes, treated with copper (I) bromide (277 mg, 1.93 mmol) and allowed to warm to room temperature over 30 minutes. A solution of 2-iodobenzonitrile (948 mg, 4.14 mmol) in pyridine (2 ml) was added and the mixture heated under reflux for 2.5 hours. The mixture was allowed to cool to room temperature and the solvent removed in vacuo. The resulting residue was purified by column chromatography eluting with a mixture of ammonia:methanol:dichloromethane (0.2:1.8:98) to afford the title compound (180 mg); MS (ES+) m/e 319 [M+H]+.
