Reaction Steps

Sodium hydride (60% disp. in mineral oil, 96 mg, 2.4 mmol) was added to a stirred solution of 3-cyclobutyl-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ol (E3) (435 mg, 2.0 mmol) and copper (I) bromide (402 mg, 2.8 mmol) in pyridine (10 ml) at 0° C. After stirring for 0.5 hour at room temperature, iodobenzene (0.45 ml, 4.0 mmol) was added and the reaction mixture was heated to reflux for 24 hours. The reaction was allowed to cool, filtered and the filtrate then concentrated in vacuo. The crude residue was dissolved with ethyl acetate and washed with water and brine. The organic layer was dried over magnesium sulfate, filtered and concentrated in vacuo and the resulting residue purified by column chromatography eluting with a mixture of 0.880 ammonia:ethanol:dichloromethane (0.25:2.25:97.5 to 1:9:90) to afford the title compound (E128); MS (ES+) m/e 294 [M+H]+.
