Reaction Steps

Acetyl chloride (54 μl) was added to a solution of 5-[[2-(2-chlorophenyl)ethyl](methyl)amino]-1-(2,3,4,5-tetrahydro-1H-3-benzazepin-7-yl)-1-pentanone (294 mg) obtained in Example 205 and triethylamine (139 μl) 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 purified by silica gel column chromatography to give a free base compound of the title compound as a pale yellow oil (280 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 (220 mg).
