Ethyl isocyanate (74 μl) was added to a solution of 5-[[2-(2-chlorophenyl)ethyl](methyl)amino]-1-(2,3,4,5-tetrahydro-1 H-3-benzazepin-7-yl)-1-pentanone (365 mg) obtained in Example 205 in tetrahydrofuran (2 ml). After stirring at room temperature for 60 minutes, water (10 g) was added, extracted with ethyl acetate, and washed with brine. The organic layer was dried over anhydrous sodium sulfate, the solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography to give a free base compound of the title compound as a pale yellow oil (330 mg). A solution of the free base compound in ethanol was treated with hydrogen chloride (ethyl acetate solution) to give the title compound as pale yellow amorphous powders (290 mg).
