Procedure

To a solution of 0.32 gm (1.1 mMol) 6-benzyloxy-3-amino-1,2,3,4-tetrahydro-9H-carbazole in 8 mL acetonitrile were added 0.30 gm (1.68 mMol) potassium carbonate, 0.25 gm (1.68 mMol) sodium iodide and 0.23 mL (1.68 mMol) 2-phenyl-1-ethyl bromide. The resulting mixture was stirred 4 hours at room temperature followed by 5 hours at reflux. The reaction mixture was cooled to room temperature and then partitioned between dichloromethane and water. The aqueous phase was extracted well with dichloromethane. All of the organic phases were combined, dried over magnesium sulfate and concentrated under reduced pressure. The residue was subjected to silica gel chromatography, eluting with 7% methanol in dichloromethane. Fractions shown to contain product were concentrated under reduced pressure to give 0.345 gm (79%) of the desired compound. A portion was converted to the corresponding hydrochloride salt,
