実験手順
A mixture of 2,3,4,5-tetrahydro-1-(p-trifluoromethylphenoxy)-3-benzazepine of Example 1 (8.5 g, 0.028 mole), 2-dimethylaminoethyl chloride hydrochloride (6.5 g, 0.045 mole) and sodium bicarbonate (18 g, 0.021 mole) in DMF (125 ml) was stirred at 60° C. for two hours. The reaction mixture was concentrated to a slurry which was stirred with water and extracted with ethyl acetate-ether. The organic extracts were washed twice with water and dried (saturated NaCl, anhydrous MgSO4). The solution was filtered and concentrated to an oil (8 g) which was converted to the dihydrochloride salt (6 g, 48% d 170° C.) by the addition of ethereal HCl. This material was recrystallized twice from a 20:1 ethyl acetate/methanol solution to yield 3-(2-dimethylaminoethyl)-1-(p-trifluoromethylphenoxy)-3-benzazepine dihydrochloride, d 137°-238° C.
