Procedure

A mixture of 7,8-dimethoxy-1-phenoxy-2,3,4,5-tetrahydro-3-benzazepine of Example 35 (4.8 g, 16 mmole) and 3-phenoxypropyl bromide (4 g, 18 mmole) in 25 ml DMF containing potassium carbonate (milled, 4.4 g, 32 mmole) was stirred at 80° C. for two hours. After cooling, the mixture was stirred with 300 ml water and was extracted with ethyl acetate-ether. The organic extract was washed with water, saturated NaCl and was dried (anhydrous MgSO4), filtered and evaporated to 9 g of an oil. This oil was purified by HPLC (silica gel, 10% ethyl acetate/dichloromethane) to give 4.7 g (68%) of 7,8-dimethoxy-3-(3-phenoxypropyl)-1-phenoxy-2,3,4,5-tetrahydro-3-benzazepine solid, m.p. 95°-100° C.
